An electronic book, also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.
In the 2000s, there was a trend of print and e-book sales moving to the Internet, where readers buy traditional paper books and e-books on websites using e-commerce systems. With print books, readers are increasingly browsing through images of the covers of books on publisher or bookstore websites and selecting and ordering titles online; the paper books are then delivered to the reader by mail or another delivery service. With e-books, users can browse through titles online, and then when they select and order titles, the e-book can be sent to them online or the user can download the e-book. At the start of 2012 in the U.S., more e-books were published online than were distributed in hardcover.
The main reasons for people buying e-books online are possibly lower prices, increased comfort (as they can buy from home or on the go with mobile devices) and a larger selection of titles. With e-books, "[e]lectronic bookmarks make referencing easier, and e-book readers may allow the user to annotate pages."  "Although fiction and non-fiction books come in e-book formats, technical material is especially suited for e-book delivery because it can be [electronically] searched" for keywords. In addition, for programming books, code examples can be copied. The amount of e-book reading is increasing in the U.S.; by 2014, 28% of adults had read an e-book, compared to 23% in 2013. This is increasing, because by 2014 50% of American adults had an e-reader or a tablet, compared to 30% owning such devices in 2013.
E-books are also referred to as "ebooks", "eBooks", "Ebooks", "e-Books", "e-journals", "e-editions" or as "digital books". The devices that are designed specifically for reading e-books are called "e-readers", "ebook device" or "eReaders".
Some trace the idea of an e-reader that would enable a reader to view books on a screen to a 1930 manifesto by Bob Brown, written after watching his first "talkie" (movie with sound). He titled it The Readies, playing off the idea of the "talkie". In his book, Brown says movies have outmaneuvered the book by creating the "talkies" and, as a result, reading should find a new medium:
“A simple reading machine which I can carry or move around, attach to any old electric light plug and read hundred-thousand-word novels in 10 minutes if I want to, and I want to.”
Brown's notion, however, was much more focused on reforming orthography and vocabulary, than on medium (“It is time to pull out the stopper” and begin “a bloody revolution of the word.”): introducing huge numbers of portmanteau symbols to replace normal words, and punctuation to simulate action or movement; so it is not clear whether this fits in the history of "e-books" or not. Later e-readers never followed a model at all like Brown's. Nevertheless, Brown predicted the miniaturization and portability of e-readers. In an article, Jennifer Schuessler writes, "The machine, Brown argued, would allow readers to adjust the type size, avoid paper cuts and save trees, all while hastening the day when words could be 'recorded directly on the palpitating ether.'" He felt the e-reader (and his notions for changing text itself) should bring a completely new life to reading. Schuessler relates it to a DJ spinning bits of old songs to create a beat or an entirely new song as opposed to just a remix of a familiar song.
The inventor of the first e-book is not widely agreed upon. Some notable candidates include the following:
In 1949, Ángela Ruiz Robles, a teacher from León, Spain, patented the Enciclopedia Mecánica, or the Mechanical Encyclopedia, a mechanical device which operated on compressed air where text and graphics were contained on spools that users would load onto rotating spindles. Her idea was to create a device which would decrease the number of books that her pupils carried to school. The final device would include audio recordings, a magnifying glass, a calculator and an electric light for night reading. Her device was never put into production but one of her prototypes is kept in the National Museum of Science and Technology in La Coruna, Spain.
The first e-book may be the Index Thomisticus, a heavily annotated electronic index to the works of Thomas Aquinas, prepared by Roberto Busa, S.J. beginning in 1949 and completed in the 1970s. Although originally stored on a single computer, a distributable CD-ROM version appeared in 1989. However, this work is sometimes omitted; perhaps because the digitized text was a means for studying written texts and developing linguistic concordances, rather than as a published edition in its own right. In 2005, the Index was published online.
Alternatively, some historians consider electronic books to have started in the early 1960s, with the NLS project headed by Doug Engelbart at Stanford Research Institute (SRI), and the Hypertext Editing System and FRESS projects headed by Andries van Dam at Brown University. FRESS documents ran on IBM mainframes and were structure-oriented rather than line-oriented; they were formatted dynamically for different users, display hardware, window sizes, and so on, as well as having automated tables of contents, indexes, and so on. All these systems also provided extensive hyperlinking, graphics, and other capabilities. Van Dam is generally thought to have coined the term "electronic book", and it was established enough to use in an article title by 1985.
FRESS was used for reading extensive primary texts online, as well as for annotation and online discussions in several courses, including English Poetry and Biochemistry. Brown's faculty made extensive use of FRESS; for example the philosopher Roderick Chisholm used it to produce several of his books. Thus in the Preface to Person and Object (1979) he writes "The book would not have been completed without the epoch-making File Retrieval and Editing System..." Brown University's work in electronic book systems continued for many years, including US Navy funded projects for electronic repair-manuals; a large-scale distributed hypermedia system known as InterMedia; a spinoff company Electronic Book Technologies that built DynaText, the first SGML-based e-reader system; and the Scholarly Technology Group's extensive work on the Open eBook standard.
Despite the extensive earlier history, several publications report Michael S. Hart as the inventor of the e-book. In 1971, the operators of the Xerox Sigma V mainframe at the University of Illinois gave Hart extensive computer-time. Seeking a worthy use of this resource, he created his first electronic document by typing the United States Declaration of Independence into a computer in plain text. Hart planned to create documents using plain text to make them as easy as possible to download and view on devices.
After Hart first adapted the Declaration of Independence into an electronic document in 1971, Project Gutenberg was launched to create electronic copies of more texts - especially books. Another early e-book implementation was the desktop prototype for a proposed notebook computer, the Dynabook, in the 1970s at PARC: a general-purpose portable personal computer capable of displaying books for reading. In 1980 the US Department of Defense began concept development for a portable electronic delivery device for technical maintenance information called project PEAM, the Portable Electronic Aid for Maintenance. Detailed specifications were completed in FY 82, and prototype development began with Texas Instruments that same year. Four prototypes were produced and delivered for testing in 1986. Tests were completed in 1987. The final summary report was produced by the US Army research Institute for the Behavioral and Social Sciences in 1989 authored by Robert Wisher and J. Peter Kincaid. A patent application for the PEAM device  was submitted by Texas Instruments titled "Apparatus for delivering procedural type instructions" was submitted Dec 4, 1985 listing John K. Harkins and Stephen H. Morriss as inventors.
In 1992, Sony launched the Data Discman, an electronic book reader that could read e-books that were stored on CDs. One of the electronic publications that could be played on the Data Discman was called The Library of the Future. Early e-books were generally written for specialty areas and a limited audience, meant to be read only by small and devoted interest groups. The scope of the subject matter of these e-books included technical manuals for hardware, manufacturing techniques, and other subjects. In the 1990s, the general availability of the Internet made transferring electronic files much easier, including e-books.
As e-book formats emerged and proliferated, some garnered support from major software companies, such as Adobe with its PDF format that was introduced in 1993. Unlike most other formats, PDF documents are generally tied to a particular dimension and layout, rather than adjusting dynamically to the current page, window, or other size. Different e-reader devices followed different formats, most of them accepting books in only one or a few formats, thereby fragmenting the e-book market even more. Due to the exclusiveness and limited readerships of e-books, the fractured market of independent publishers and specialty authors lacked consensus regarding a standard for packaging and selling e-books.
Meanwhile, scholars formed the Text Encoding Initiative, which developed consensus guidelines for encoding books and other materials of scholarly interest for a variety of analytic uses as well as reading, and countless literary and other works have been developed using the TEI approach. In the late 1990s, a consortium formed to develop the Open eBook format as a way for authors and publishers to provide a single source-document which many book-reading software and hardware platforms could handle. Several scholars from the TEI were closely involved in the early development of Open eBook . Focused on portability, Open eBook as defined required subsets of XHTML and CSS; a set of multimedia formats (others could be used, but there must also be a fallback in one of the required formats), and an XML schema for a "manifest", to list the components of a given e-book, identify a table of contents, cover art, and so on. This format led to the open format EPUB. Google Books has converted many public domain works to this open format.
In 2010, e-books continued to gain in their own specialist and underground markets. Many e-book publishers began distributing books that were in the public domain. At the same time, authors with books that were not accepted by publishers offered their works online so they could be seen by others. Unofficial (and occasionally unauthorized) catalogs of books became available on the web, and sites devoted to e-books began disseminating information about e-books to the public. Nearly two-thirds of the U.S. Consumer e-book publishing market are controlled by the "Big Five". The "Big Five" publishers include: Hachette, HarperCollins, Macmillan, Penguin Random House and Simon & Schuster.
US Libraries began providing free e-books to the public in 1998 through their websites and associated services, although the e-books were primarily scholarly, technical or professional in nature, and could not be downloaded. In 2003, libraries began offering free downloadable popular fiction and non-fiction e-books to the public, launching an E-book lending model that worked much more successfully for public libraries. The number of library e-book distributors and lending models continued to increase over the next few years. From 2005 to 2008 libraries experienced 60% growth in e-book collections. In 2010, a Public Library Funding and Technology Access Study found that 66% of public libraries in the US were offering e-books, and a large movement in the library industry began seriously examining the issues related to lending e-books, acknowledging a tipping point of broad e-book usage.
The US National Library of Medicine has for many years provided PubMed, a nearly-exhaustive bibliography of medical literature. In early 2000, NLM started PubMed Central, which provides full-text e-book versions of many medical journal articles and books, through cooperation with scholars and publishers in the field. Pubmed Central now provides archiving and access to over 4.1 million articles, maintained in a standard XML format known as the Journal Article Tag Suite (or "JATS").
However, some publishers and authors have not endorsed the concept of electronic publishing, citing issues with user demand, copyright piracy and challenges with proprietary devices and systems. In a survey of interlibrary loan librarians it was found that 92% of libraries held e-books in their collections and that 27% of those libraries had negotiated interlibrary loan rights for some of their e-books. This survey found significant barriers to conducting interlibrary loan for e-books. Demand-driven acquisition (DDA) has been around for a few years in public libraries, which allows vendors to streamline the acquisition process by offering to match a library's selection profile to the vendor's e-book titles. The library's catalog is then populated with records for all the e-books that match the profile. The decision to purchase the title is left to the patrons, although the library can set purchasing conditions such as a maximum price and purchasing caps so that the dedicated funds are spent according to the library's budget. The 2012 meeting of the Association of American University Presses included a panel on patron-drive acquisition (PDA) of books produced by university presses based on a preliminary report by Joseph Esposito, a digital publishing consultant who has studied the implications of PDA with a grant from the Andrew W. Mellon Foundation.
Although the demand for e-book services in libraries has grown in the decades of the 2000s and 2010s, difficulties keep libraries from providing some e-books to clients. Publishers will sell e-books to libraries, but they only give libraries a limited license to the title in most cases. This means the library does not own the electronic text but that they can circulate it either for a certain period of time or for a certain number of check outs, or both. When a library purchases an e-book license, the cost is at least three times what it would be for a personal consumer. E-book licenses are more expensive than paper-format editions because publishers are concerned that an e-book that is sold could theoretically be read and/or checked out by a huge number of users, which could adversely affect sales. However, some studies have found the opposite effect (for example, Hilton and Wikey 2010)
An e-reader, also called an e-book reader or e-book device, is a mobile electronic device that is designed primarily for the purpose of reading e-books and digital periodicals. An e-reader is similar in form, but more limited in purpose than a tablet. In comparison to tablets, many e-readers are better than tablets for reading because they are more portable, have better readability in sunlight and have longer battery life. In July 2010, online bookseller Amazon.com reported sales of e-books for its proprietary Kindle outnumbered sales of hardcover books for the first time ever during the second quarter of 2010, saying it sold 140 e-books for every 100 hardcover books, including hardcovers for which there was no digital edition. By January 2011, e-book sales at Amazon had surpassed its paperback sales. In the overall US market, paperback book sales are still much larger than either hardcover or e-book; the American Publishing Association estimated e-books represented 8.5% of sales as of mid-2010, up from 3% a year before. At the end of the first quarter of 2012, e-book sales in the United States surpassed hardcover book sales for the first time.
Until late 2013, use of an e-reader was not allowed on airplanes during takeoff and landing by the FAA. In November 2013, the FAA allowed use of e-readers on airplanes at all times if it is in Airplane Mode, which means all radios turned off, and Europe followed this guidance the next month. In 2014, The New York Times predicted that by 2018 e-books will make up over 50% of total consumer publishing revenue in the United States and Great Britain.
Some of the major book retailers and multiple third-party developers offer free (and in some third-party cases, premium paid) e-reader software applications (apps) for the Mac and PC computers as well as for Android, Blackberry, iPad, iPhone, Windows Phone and Palm OS devices to allow the reading of e-books and other documents independently of dedicated e-book devices. Examples are apps for the Amazon Kindle, Barnes & Noble Nook, iBooks, Kobo eReader and Sony Reader.
Writers and publishers have many formats to choose from when publishing e-books. Each format has advantages and disadvantages. The most popular e-readers and their natively supported formats are shown below:
|Reader||Native e-book formats|
|Amazon Kindle and Fire tablets||AZW, AZW3, KF8, non-DRM MOBI, PDF, PRC, TXT|
|Barnes & Noble Nook and Nook Tablet||EPUB, PDF|
|Apple iPad||EPUB, IBA (Multitouch books made via iBooks Author), PDF|
|Sony Reader||EPUB, PDF, TXT, RTF, DOC, BBeB|
|Kobo eReader and Kobo Arc||EPUB, PDF, TXT, RTF, HTML, CBR (comic), CBZ (comic)|
|PocketBook Reader and PocketBook Touch||EPUB DRM, EPUB, PDF DRM, PDF, FB2, FB2.ZIP, TXT, DJVU, HTM, HTML, DOC, DOCX, RTF, CHM, TCR, PRC (MOBI)|
Most e-book publishers do not warn their customers about the possible implications of the digital rights management tied to their products. Generally, they claim that digital rights management is meant to prevent illegal copying of the e-book. However, in many cases, it is also possible that digital rights management will result in the complete denial of access by the purchaser to the e-book. The e-books sold by most major publishers and electronic retailers, which are Amazon.com, Google, Barnes & Noble, Kobo Inc. and Apple Inc., are DRM-protected and tied to the publisher's e-reader software or hardware. The first major publisher to omit DRM was Tor Books, one of the largest publishers of science fiction and fantasy, in 2012. Smaller e-book publishers such as O'Reilly Media, Carina Press and Baen Books had already forgone DRM previously.
Some e-books are produced simultaneously with the production of a printed format, as described in electronic publishing, though in many instances they may not be put on sale until later. Often, e-books are produced from pre-existing hard-copy books, generally by document scanning, sometimes with the use of robotic book scanners, having the technology to quickly scan books without damaging the original print edition. Scanning a book produces a set of image files, which may additionally be converted into text format by an OCR program. Occasionally, as in some projects, an e-book may be produced by re-entering the text from a keyboard. Sometimes only the electronic version of a book is produced by the publisher. It is possible to release an e-book chapter by chapter as each chapter is written. This is useful in fields such as information technology where topics can change quickly in the months that it takes to write a typical book. It is also possible to convert an electronic book to a printed book by print on demand. However, these are exceptions as tradition dictates that a book be launched in the print format and later if the author wishes an electronic version is produced. The New York Times keeps a list of best-selling e-books, for both fiction and non-fiction.
All of the e-readers and reading apps are capable of tracking e-book reading data, and the data could contain which e-books users open, how long the users spend reading each e-book and how much of each e-book is finished. In December 2014, Kobo released e-book reading data collected from over 21 million of its users worldwide. Some of the results were that only 44.4% of UK readers finished the bestselling e-book The Goldfinch and the 2014 top selling e-book in the UK, "One Cold Night", was finished by 69% of readers; this is evidence that while popular e-books are being completely read, some e-books are only sampled.
In the space that a comparably sized physical book takes up, an e-reader can contain thousands of e-books, limited only by its memory capacity. Depending on the device, an e-book may be readable in low light or even total darkness. Many e-readers have a built-in light source, can enlarge or change fonts, use text-to-speech software to read the text aloud for visually impaired, elderly or dyslexic people or just for convenience. Additionally, e-readers allow readers to look up words or find more information about the topic immediately using an online dictionary. Amazon reports that 85% of its e-book readers look up a word while reading.
Printed books use three times more raw materials and 78 times more water to produce when compared to e-books. While an e-reader costs more than most individual books, e-books may have a lower cost than paper books. E-books may be printed for less than the price of traditional books using on-demand book printers. Moreover, numerous e-books are available online free of charge on sites such as Project Gutenberg. For example, all books printed before 1923 are in the public domain in the United States, which enables websites to host ebook versions of such titles for free.
Depending on possible digital rights management, e-books (unlike physical books) can be backed up and recovered in the case of loss or damage to the device on which they are stored, a new copy can be downloaded without incurring an additional cost from the distributor, as well as being able to synchronize the reading location, highlights and bookmarks across several devices.
There may be a lack of privacy for the user's e-book reading activities; for example, Amazon knows the user's identity, what the user is reading, whether the user has finished the book, what page the user is on, how long the user has spent on each page, and which passages the user may have highlighted. One obstacle to wide adoption of the e-book is that a large portion of people value the printed book as an object itself, including aspects such as the texture, smell, weight and appearance on the shelf. Print books are also considered valuable cultural items, and symbols of liberal education and the humanities. Kobo found that 60% of e-books that are purchased from their e-book store are never opened and found that the more expensive the book is, the more likely the reader would at least open the e-book.
Joe Queenan has written about the pros and cons of e-books:
Electronic books are ideal for people who value the information contained in them, or who have vision problems, or who like to read on the subway, or who do not want other people to see how they are amusing themselves, or who have storage and clutter issues, but they are useless for people who are engaged in an intense, lifelong love affair with books. Books that we can touch; books that we can smell; books that we can depend on.
Apart from all the emotional and habitual aspects, there are also some readability and usability issues that need to be addressed by publishers and software developers. Many e-book readers who complain about eyestrain, lack of overview and distractions could be helped if they could use a more suitable device or a more user friendly reading application, but when they buy or borrow a DRM-protected e-book, they often have to read the book on the default device or application, even if it has insufficient functionality.
While a paper book is vulnerable to various threats, including water damage, mold and theft, e-books files may be corrupted, deleted or otherwise lost as well as pirated. Where the ownership of a paper book is fairly straightforward (albeit subject to restrictions on renting or copying pages, depending on the book), the purchaser of an e-book's digital file has conditional access with the possible loss of access to the e-book due to digital rights management provisions, copyright issues, the provider's business failing or possibly if user's credit card expired.
In 2015, the Author Earnings Report estimated that Amazon held a 74% market share of the e-books sold in the U.S. By the end of 2016, that year's Report estimated that Amazon held 80% of the e-book market share in the U.S.
In 2013, Carrenho estimates that e-books would have a 15% market share in Spain in 2015.
According to Nielsen Book Research, e-book share went from 20% to 33% between 2012 and 2014, but down to 29% in the first quarter of 2015. Amazon-published and self-published titles accounted for 17 million of those books - worth £58m – in 2014, representing 5% of the overall book market and 15% of the digital market. The volume and value sales are similar to 2013 but up 70% since 2012.
The Wischenbart Report 2015 estimates the e-book market share to be 4.3%.
The Brazilian e-book market is only emerging. Brazilians are technology savvy, and that attitude is shared by the government. In 2013, around 2.5% of all trade titles sold were in digital format. This was a 400% growth over 2012 when only 0.5% of trade titles were digital. In 2014, the growth was slower, Brazil had 3.5% of its trade titles being sold as e-books.
The Wischenbart Report 2015 estimates the e-book market share to be around 1%.
Public domain books are those whose copyrights have expired, meaning they can be copied, edited, and sold freely without restrictions. Many of them can be downloaded for free from websites like the Internet Archive in formats many E-readers support, like PDF, TXT, and EPUB. Books in other formats may be converted to an e-reader compatible format using for instance Calibre.
Digital publishing and print on demand have significantly reduced the cost of producing a book.
Amazon.com, Inc., doing business as Amazon (), is a multinational technology company focusing in e-commerce, cloud computing, and artificial intelligence in Seattle, Washington.
Amazon is the largest e-commerce marketplace and cloud computing platform in the world as measured by revenue and market capitalization. Amazon.com was founded by Jeff Bezos on July 5, 1994, and started as an online bookstore but later diversified to sell video downloads/streaming, MP3 downloads/streaming, audiobook downloads/streaming, software, video games, electronics, apparel, furniture, food, toys, and jewelry. The company also owns a publishing arm, Amazon Publishing, a film and television studio, Amazon Studios, produces consumer electronics lines including Kindle e-readers, Fire tablets, Fire TV, and Echo devices, and is the world's largest provider of cloud infrastructure services (IaaS and PaaS) through its AWS subsidiary. Amazon has separate retail websites for some countries and also offers international shipping of some of its products to certain other countries. 100 million people subscribe to Amazon Prime.Amazon is the largest Internet company by revenue in the world and the second largest employer in the United States. In 2015, Amazon surpassed Walmart as the most valuable retailer in the United States by market capitalization. In 2017, Amazon acquired Whole Foods Market for $13.4 billion, which vastly increased Amazon's presence as a brick-and-mortar retailer. The acquisition was interpreted by some as a direct attempt to challenge Walmart's traditional retail stores.Amazon Kindle
The Amazon Kindle is a series of e-readers designed and marketed by Amazon. Amazon Kindle devices enable users to browse, buy, download, and read e-books, newspapers, magazines and other digital media via wireless networking to the Kindle Store. The hardware platform, developed by Amazon subsidiary Lab126, began as a single device in 2007 and now comprises a range of devices, including e-readers with E Ink electronic paper displays and Kindle applications on all major computing platforms. All Kindle devices integrate with Kindle Store content, and as of March 2018, the store has over six million e-books available in the United States.Apple Books
Apple Books is an e-book reading and store application by Apple Inc. for its iOS and macOS operating systems and devices. It was announced, under the name iBooks, in conjunction with the iPad on January 27, 2010, and was released for the iPhone and iPod Touch in mid-2010, as part of the iOS 4 update. Initially, iBooks was not pre-loaded onto iOS devices, but users could install it free of charge from the iTunes App Store. With the release of iOS 8, it became an integrated app. On June 10, 2013, at the Apple Worldwide Developers Conference, Craig Federighi announced that iBooks would also be provided with OS X Mavericks in fall 2013. Prior to iOS 12 and macOS Mojave, the application was named iBooks.
It primarily receives EPUB content from the iBooks Store, but users can also add their own EPUB and PDF files via data synchronization with iTunes. Additionally, the files can be downloaded to iBooks through Safari or Apple Mail. It is also capable of displaying e-books that incorporate multimedia. According to product information as of March 2010, iBooks will be able to "read the contents of any page [to the user]" using VoiceOver.On January 19, 2012 at an education-focused special event in New York City, Apple announced the free release of iBooks 2, which can operate in landscape mode and allows for interactive reading. In addition, a new application, iBooks Author, was announced for the Mac App Store, allowing anyone to create interactive textbooks for reading in iBooks; and the iBooks Store was expanded with a textbook category. The iBooks Author Conference, the annual gathering of digital content creators around Apple's iBooks Author, has convened since 2015.iBooks was renamed to Apple Books alongside the release of iOS 12 and macOS Mojave in September 2018. It features a new variation of the San Francisco typeface known as "SF Serif."Author
An author is the creator or originator of any written work such as a book or play, and is thus also a writer. More broadly defined, an author is "the person who originated or gave existence to anything" and whose authorship determines responsibility for what was created.Book
As a physical object, a book is a stack of usually rectangular pages (made of papyrus, parchment, vellum, or paper) oriented with one edge tied, sewn, or otherwise fixed together and then bound to the flexible spine of a protective cover of heavier, relatively inflexible material. The technical term for this physical arrangement is codex (in the plural, codices). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its immediate predecessor, the scroll. A single sheet in a codex is a leaf, and each side of a leaf is a page.
As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and a still considerable, though not so extensive, investment of time to read. This sense of book has a restricted and an unrestricted sense. In the restricted sense, a book is a self-sufficient section or part of a longer composition, a usage that reflects the fact that, in antiquity, long works had to be written on several scrolls, and each scroll had to be identified by the book it contained. So, for instance, each part of Aristotle's Physics is called a book, as of course the Bible encompasses many different books. In the unrestricted sense, a book is the compositional whole of which such sections, whether called books or chapters or parts, are parts.
The intellectual content in a physical book need not be a composition, nor even be called a book. Books can consist only of drawings, engravings, or photographs, or such things as crossword puzzles or cut-out dolls. In a physical book the pages can be left blank or can feature an abstract set of lines as support for on-going entries, i.e., an account book, an appointment book, a log book, an autograph book, a notebook, a diary or day book, or a sketch book. Some physical books are made with pages thick and sturdy enough to support other physical objects, like a scrapbook or photograph album. Books may be distributed in electronic form as e-books and other formats.
Although in ordinary academic parlance a monograph is understood to be a specialist academic work, rather than a reference work on a single scholarly subject, in library and information science monograph denotes more broadly any non-serial publication complete in one volume (book) or a finite number of volumes (even a novel like Proust's seven-volume In Search of Lost Time), in contrast to serial publications like a magazine, journal, or newspaper. An avid reader or collector of books or a book lover is a bibliophile or colloquially, "bookworm". A shop where books are bought and sold is a bookshop or bookstore. Books are also sold elsewhere. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 distinct titles had been published. In some wealthier nations, the sale of printed books has decreased because of the use of e-books, though sales of e-books declined in the first half of 2015.Braille e-book
A braille e-book is a refreshable braille display using electroactive polymers or heated wax rather than mechanical pins to raise braille dots on a display. Though not inherently expensive, due to the small scale of production they have not been shown to be economical.Castle (TV series)
Castle is an American crime-comedy-drama television series, which aired on ABC for a total of eight seasons from March 9, 2009, to May 16, 2016. The series was produced jointly by Beacon Pictures and ABC Studios.
Created by Andrew W. Marlowe, it primarily traces the lives of Richard Castle (Nathan Fillion), a best-selling mystery novelist, and Kate Beckett (Stana Katic), a homicide detective, as they solve various unusual crimes in New York City. Detective Beckett is initially infuriated at the thought of working with a writer and goes to great lengths to keep him out of her way. However, the two soon start developing feelings for each other. The overarching plot of the series focused on the romance between the two lead characters and their ongoing investigation of the murder of Beckett's mother.
On May 12, 2016, it was announced that despite some cast members signing one-year contracts for a potential ninth season, the show was canceled.E-reader
An e-reader, also called an e-book reader or e-book device, is a mobile electronic device that is designed primarily for the purpose of reading digital e-books and periodicals.Any device that can display text on a screen may act as an e-reader, but specialized e-reader devices may optimize portability, readability (especially in sunlight), and battery life for this purpose. Their main advantages over printed books are portability since an e-reader is capable of holding thousands of books while weighing less than one and the convenience provided due to add-on features in these devices.Google Play
Google Play (previously Android Market) is a digital distribution service operated and developed by Google LLC. It serves as the official app store for the Android operating system, allowing users to browse and download applications developed with the Android software development kit (SDK) and published through Google. Google Play also serves as a digital media store, offering music, books, movies, and television programs. It previously offered Google hardware devices for purchase until the introduction of a separate online hardware retailer, Google Store, on March 11, 2015, and it also offered news publications and magazines before the revamp of Google News in May 15, 2018.
Applications are available through Google Play either free of charge or at a cost. They can be downloaded directly on an Android device through the Play Store mobile app or by deploying the application to a device from the Google Play website. Applications exploiting hardware capabilities of a device can be targeted to users of devices with specific hardware components, such as a motion sensor (for motion-dependent games) or a front-facing camera (for online video calling). The Google Play store had over 82 billion app downloads in 2016 and has reached over 3.5 million apps published in 2017. It has been the subject of multiple issues concerning security, in which malicious software has been approved and uploaded to the store and downloaded by users, with varying degrees of severity.
Google Play was launched on March 6, 2012, bringing together the Android Market, Google Music, and the Google eBookstore under one brand, marking a shift in Google's digital distribution strategy. The services included in the Google Play are Google Play Books, Google Play Games, Google Play Movies & TV, Google Play Music. Following their re-branding, Google has gradually expanded the geographical support for each of the services.International Standard Book Number
The International Standard Book Number (ISBN) is a numeric commercial book identifier which is intended to be unique. Publishers purchase ISBNs from an affiliate of the International ISBN Agency.An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007. The method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country.
The initial ISBN configuration of recognition was generated in 1967, based upon the 9-digit Standard Book Numbering (SBN) created in 1966. The 10-digit ISBN format was developed by the International Organization for Standardization (ISO) and was published in 1970 as international standard ISO 2108 (the SBN code can be converted to a ten-digit ISBN by prefixing it with a zero digit "0").
Privately published books sometimes appear without an ISBN. The International ISBN agency sometimes assigns such books ISBNs on its own initiative.Another identifier, the International Standard Serial Number (ISSN), identifies periodical publications such as magazines; and the International Standard Music Number (ISMN) covers for musical scores.Kindle Store
The Kindle Store is an online e-book e-commerce store operated by Amazon as part of its retail website and can be accessed from any Amazon Kindle, Fire tablet or Kindle mobile app. At the launch of the Kindle in November 2007, the store had more than 88,000 digital titles available. This number increased to more than 275,000 by late 2008, and exceeded 765,000 by August 2011. In July 2014, there were over 2.7 million titles available at the U.S. store and as of March 2018 there are over six million titles available in the U.S. Content from the store is purchased online and downloaded using either Wi-Fi or Amazon's 3G Whispernet to bring the content to the user's device. One of the innovations Amazon brought to the store was one-click purchasing that allowed users to quickly purchase an e-book. The Kindle Store uses a recommendation engine that looks at purchase history, browsing history, and reading activity, and then suggests material it thinks the user will like.Project Gutenberg
Project Gutenberg (PG) is a volunteer effort to digitize and archive cultural works, to "encourage the creation and distribution of eBooks". It was founded in 1971 by American writer Michael S. Hart and is the oldest digital library. Most of the items in its collection are the full texts of public domain books. The project tries to make these as free as possible, in long-lasting, open formats that can be used on almost any computer. As of 23 June 2018, Project Gutenberg reached 57,000 items in its collection of free eBooks.The releases are available in plain text but, wherever possible, other formats are included, such as HTML, PDF, EPUB, MOBI, and Plucker. Most releases are in the English language, but many non-English works are also available. There are multiple affiliated projects that are providing additional content, including regional and language-specific works. Project Gutenberg is also closely affiliated with Distributed Proofreaders, an Internet-based community for proofreading scanned texts.Scribd

Self-publishing is the publication of media by its author without the involvement of an established publisher. In common parlance, the term usually refers to physical written media, such as books and magazines, or digital media, such as e-books and websites. It can also apply to albums, pamphlets, brochures, video content, zines, or uploading images to a website.Unlike the traditional publishing model, in which control of the publication is shared with a publisher, the author controls the entire process, including design, price, distribution, marketing, and public relations. The author may perform these activities themselves or they may outsource these tasks. In traditional publishing, the publisher bears the costs, such as editing, marketing, and paying advances, and reaps a substantial share of the profits; by comparison, in self-publishing, the author bears all of these costs but earns a higher share of the profit.
The $1 billion market of self-publishing has changed considerably in the past two decades with new technologies such as the Internet providing increasing alternatives to traditional publishing. Self-publishing is increasingly becoming the first choice for writers. Most self-published books sell very few copies, although there are approximately a dozen books that sell into the millions. The quality of self-published works varies considerably, with many low quality titles on the market.Vagina
In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vulva to the cervix. The outer vaginal opening is normally partly covered by a membrane called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow (menses), which occurs in humans and closely related primates as part of the monthly menstrual cycle.
Although research on the vagina is especially lacking for different animals, its location, structure and size is documented as varying among species. Female mammals usually have two external openings in the vulva, the urethral opening for the urinary tract and the vaginal opening for the genital tract. This is different from male mammals, who usually have a single urethral opening for both urination and reproduction. The vaginal opening is much larger than the nearby urethral opening, and both are protected by the labia in humans. In amphibians, birds, reptiles and monotremes, the cloaca is the single external opening for the gastrointestinal tract, the urinary, and reproductive tracts.
To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, enabling fertilization. Along with pleasure and bonding, women's sexual behavior with others (which can include heterosexual or lesbian sexual activity) can result in sexually transmitted infections (STIs), the risk of which can be reduced by recommended safe sex practices. Other health issues may also affect the human vagina.
The vagina and vulva have evoked strong reactions in societies throughout history, including negative perceptions and language, cultural taboos, and their use as symbols for female sexuality, spirituality, or regeneration of life. In common speech, the word vagina is often used to refer to the vulva or to the female genitals in general. By its dictionary and anatomical definitions, however, vagina refers exclusively to the specific internal structure, and understanding the distinction can improve knowledge of the female genitalia and aid in healthcare communication.Wattpad
Wattpad is an Internet community for readers and writers to publish new user-generated stories in different genres, including classics, general fiction, historical fiction, non-fiction, poetry, fanfiction, spiritual, humor, and teen fiction. It aims to create social communities around stories for both amateur and established writers.The platform claims to have an audience of more than 70 million users, who can directly interact with the writers and share their opinions with fellow readers. Although available in over 50 languages, 77% of its content is written in English. A number of Wattpad users are translating stories to continue to build the platform.Wikibooks
Wikibooks (previously called Wikimedia Free Textbook Project and Wikimedia-Textbooks) is a wiki-based Wikimedia project hosted by the Wikimedia Foundation for the creation of free content e-book textbooks and annotated texts that anyone can edit.Wikisource
Wikisource is an online digital library of free content textual sources on a wiki, operated by the Wikimedia Foundation. Wikisource is the name of the project as a whole and the name for each instance of that project (each instance usually representing a different language); multiple Wikisources make up the overall project of Wikisource. The project's aims are to host all forms of free text, in many languages, and translations. Originally conceived as an archive to store useful or important historical texts (its first text was the Déclaration universelle des Droits de l'Homme), it has expanded to become a general-content library. The project officially began in November 24, 2003 under the name Project Sourceberg, a play on the famous Project Gutenberg. The name Wikisource was adopted later that year and it received its own domain name seven months later. The project has come under criticism for lack of reliability but it is also cited by organisations such as the National Archives and Records Administration.The project holds works that are either in the public domain or freely licensed; professionally published works or historical source documents, not vanity products; and are verifiable. Verification was initially made offline, or by trusting the reliability of other digital libraries. Now works are supported by online scans via the ProofreadPage extension, which ensures the reliability and accuracy of the project's texts.
Some individual Wikisources, each representing a specific language, now only allow works backed up with scans. While the bulk of its collection are texts, Wikisource as a whole hosts other media, from comics to film to audio books. Some Wikisources allow user-generated annotations, subject to the specific policies of the Wikisource in question.
