OAIster is an online combined bibliographic catalogue of open access material aggregated using OAI-PMH.[1]

It began at the University of Michigan in 2002 funded by a grant from the Andrew W. Mellon Foundation and with the purpose of establishing a retrieval service for publicly available digital library resources provided by the research library community. During its tenure at the University of Michigan, OAIster grew to become one of the largest aggregations of records pointing to open access collections in the world.

In 2009, OCLC[2] formed a partnership with the University of Michigan to provide continued access to open access collections aggregated in OAIster. Since OCLC began managing OAIster, it has grown to include over 30 million records contributed by over 1,500 organizations. OCLC is evolving OAIster to a model of self-service contribution for all open access digital repositories to ensure the long-term sustainability of this rich collection of open access materials.

OAIster data is harvested from Open Archives Initiative (OAI)-compliant digital libraries, institutional repositories, and online journals using the self-service WorldCat Digital Collection Gateway.

OAIster.worldcat.org is a freely accessible OCLC site for searching the millions of OAIster records alone. The records will continue to be indexed in OCLC's WorldCat, and will be integrated in WorldCat.org search results along with records from thousands of libraries worldwide. They also will continue to be included in WorldCat Local and WorldCat Local "quick start" search results, and will continue to be available via other OCLC Discovery services.

Gulf of Panama

The Gulf of Panama (Spanish: Golfo de Panamá) is a gulf in the Pacific Ocean, near the southern coast of Panama. It has a maximum width of 250 kilometres (160 mi), a maximum depth of 220 metres (720 ft) and the size of 2,400 square kilometres (930 sq mi). The Panama Canal connects the Gulf of Panama with the Caribbean Sea and the Pacific Ocean. The Panamanian capital Panama City is the main urban centre on the gulf shore.

The gulf itself also contains a few minor gulfs, with Panama Bay to the north, Gulf of Parita to the west and Gulf of San Miguel to the east. The gulf has a few islands and on the coast there are a few important ports, like Panama City, La Palma and Chitrè. The Pearl Islands archipelago is a group of over two hundred islands situated to the east in the gulf.

Panama’s largest river, Tuira, flows south into the Gulf of San Miguel.

List of academic databases and search engines

This page contains a representative list of major databases and search engines useful in an academic setting for finding and accessing articles in academic journals, institutional repositories, archives, or other collections of scientific and other articles.

As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see:

the general list of search engines for all-purpose search engines that can be used for academic purposes

the article about bibliographic databases for information about databases giving bibliographic information about finding books and journal articles.Note that "free" or "subscription" can refer both to the availability of the

database or of the journal articles included. This has been indicated as precisely as possible in the lists below.

List of open-access projects

Some of the most important open-access publishing projects or lists of such projects are listed below.


OCLC Online Computer Library Center, Incorporated d/b/a OCLC is an American nonprofit cooperative organization "dedicated to the public purposes of furthering access to the world's information and reducing information costs". It was founded in 1967 as the Ohio College Library Center. OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog (OPAC) in the world. OCLC is funded mainly by the fees that libraries have to pay for its services (around $200 million annually as of 2016). OCLC also maintains the Dewey Decimal Classification system.


OpenDOAR: Directory of Open Access Repositories is a UK-based website that lists academic open access repositories. It is searchable by locale, content and other measures. The service does not require complete repository details and does not search repositories' metadata.OpenDOAR is maintained by the University of Nottingham under the SHERPA umbrella of services and was developed in collaboration with Lund University. The project is funded by the Open Science Institute, Jisc, the Consortium of Research Libraries (CURL) and SPARC Europe.

As of 2015, OpenDOAR and the UK-based Registry of Open Access Repositories (ROAR) "are considered the two leading open access directories worldwide. ROAR is the larger directory and allows direct submissions to the directory. OpenDOAR controls submission of materials and is dependent on the discretion of its staff. OpenDOAR requires open access of scholarly publications; whereas ROAR allows other types of materials to be included. ROAR allows filtering by country, type of repository, and sorting by repository name."

Open Archives Initiative

The Open Archives Initiative (OAI) is an organization to develop and apply technical interoperability standards for archives to share catalog information (metadata). It attempts to build a "low-barrier interoperability framework" for archives (institutional repositories) containing digital content (digital libraries). It allows people (service providers) to harvest metadata (from data providers). This metadata is used to provide "value-added services", often by combining different data sets.

OAI has been involved xa in developing a technological framework and interoperability standards for enhancing access to eprint archives, which make scholarly communications like academic journals available, associated with the open access publishing movement. The relevant technology and standards are applicable beyond scholarly publishing.

The OAI technical infrastructure, specified in the Protocol for Metadata Harvesting (OAI-PMH) version 2.0, defines a mechanism for data providers to expose their metadata. This protocol mandates that individual archives map their metadata to the Dublin Core, a common metadata set for this purpose. OAI standards allow a common way to provide content, and part of those standards is that the content has metadata that describes the items in Dublin Core format. Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of web resources.

Funding for the initiative comes from the Andrew W. Mellon Foundation, Coalition for Networked Information (CNI), Digital Library Federation (DLF), National Science Foundation (NSF), the Alfred P. Sloan Foundation, and other organizations.

Open Archives Initiative Protocol for Metadata Harvesting

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a protocol developed for harvesting metadata descriptions of records in an archive so that services can be built using metadata from many archives. An implementation of OAI-PMH must support representing metadata in Dublin Core, but may also support additional representations.The protocol is usually just referred to as the OAI Protocol.

OAI-PMH uses XML over HTTP. Version 2.0 of the protocol was released in 2002; the document was last updated in 2015. It has a Creative Commons license BY-SA.

Open access

Open access (OA) is a mechanism by which research outputs are distributed online, free of cost or other barriers, and, in its most precise meaning, with the addition of an open license applied to promote reuse.Academic articles (as historically seen in print-based academic journals) have been the main focus of the movement. Conventional (non-open access) journals cover publishing costs through access tolls such as subscriptions, site licenses or pay-per-view charges. Open access can be applied to all forms of published research output, including peer-reviewed and non peer-reviewed academic journal articles, conference papers, theses, book chapters, and monographs.


In academic publishing, a preprint is a version of a scholarly or scientific paper that precedes formal peer review and publication in a peer-reviewed scholarly or scientific journal. The preprint may be available, often as a non-typeset version available free, before and/or after a paper is published in a journal.

She Ventures and He Wins

She Ventures and He Wins (1696) is a comedy in five acts written by a Young Woman under the pseudonym of "Ariadne". The author, who is referred to by most documents and historians by her pseudonym, caused an uproar between the theaters of the area and, because of her writing, this play helped to start the theatrical tradition of cross-dressing. Ariadne is noted as writing with humor and wit that matches that of her contemporaries. The original manuscript mentioned it was an adaptation of a "small novel", which has since been discovered to be The Fair Extravagant by Alexander Oldys, an unknown story that had been almost unheard of since its publication. Much of the plot remains the same with detail, some plot points, and characters changed. The main character in the Oldys text's name is Ariadne.

Timeline of the open-access movement

Union catalog

A union catalog is a combined library catalog describing the collections of a number of libraries. Union catalogs have been created in a range of media, including book format, microform, cards and more recently, networked electronic databases. Print union catalogs are typically arranged by title, author or subject (often employing a controlled vocabulary); electronic versions typically support keyword and Boolean queries.

Union catalogs are useful to librarians, as they assist in locating and requesting materials from other libraries through interlibrary loan service. They also allow researchers to search through collections to which they would not otherwise have access, such as manuscript collections.

The largest union catalog ever printed is the American National Union Catalog Pre-1956 Imprints (NUC), completed in 1981. This achievement has since been superseded by the creation of union catalogs in the form of electronic databases, of which the largest is OCLC's WorldCat. Another example is Copac provided by Research Libraries UK. A third example is AMICUS, provided by Library and Archives Canada.
