The New Grove Dictionary of Music and Musicians is an encyclopedic dictionary of music and musicians. Along with the German-language Musik in Geschichte und Gegenwart, it is one of the largest reference works on western music. Originally published under the title A Dictionary of Music and Musicians, and later as Grove's Dictionary of Music and Musicians, it has gone through several editions since the 19th century and is widely used. In recent years it has been made available as an electronic resource called Grove Music Online, which is now an important part of Oxford Music Online.

A Dictionary of Music and Musicians was first published in four volumes (1879, 1880, 1883, 1889) edited by George Grove with an Appendix edited by J. A. Fuller Maitland in the fourth volume. An Index edited by Mrs. E. Wodehouse was issued as a separate volume in 1890. In 1900, minor corrections were made to the plates and the entire series was reissued in four volumes, with the index added to volume 4. The original edition and the reprint are now freely available online. Grove limited the chronological span of his work to begin at 1450 while continuing up to the present day.
The second edition (Grove II), in five volumes, was edited by Fuller Maitland and published from 1904 to 1910, this time as Grove's Dictionary of Music and Musicians. The individual volumes of the second edition were reprinted many times. An American Supplement edited by Waldo Selden Pratt and Charles N. Boyd was added in 1920. This edition removed the first edition's beginning date of 1450, though important earlier composers and theorists are still missing from this edition. These volumes are also now freely available online. 
The fourth edition (Grove IV), also edited by Colles, was published in 1940 in five volumes (a reprint of the third edition, with some corrections). In addition to the American Supplement, Macmillan also published (in New York and London) a Supplementary Volume edited by Colles.
The fifth edition (Grove V), in nine volumes, was edited by Eric Blom and published in 1954. This was the most thoroughgoing revision of the work since its inception, with many articles rewritten in a more modern style and a large number of entirely new articles. Many of the articles were written by Blom personally, or translated by him. An additional Supplementary Volume, prepared for the most part by Eric Blom, followed in 1961. Blom died in 1959, and the Supplementary Volume was completed by Denis Stevens. The fifth edition was reprinted in 1966, 1968, 1970, 1973, and 1975.
The next edition was published in 1980 under the name The New Grove Dictionary of Music and Musicians and was greatly expanded to 20 volumes with 22,500 articles and 16,500 biographies. Its senior editor was Stanley Sadie with Nigel Fortune also serving as one of the main editors for the publication.
It was reprinted with minor corrections each subsequent year until 1995, except 1982 and 1983. In the mid-1990s, the hardback set sold for about $2,300. A paperback edition was reprinted in 1995 which sold for $500.
Some sections of The New Grove were also issued as small sets and individual books on particular topics. These typically were enhanced with expanded and updated material and included individual and grouped composer biographies, a four-volume dictionary of American music (1984; revised 2013, 8 vols.), a three-volume dictionary of musical instruments (1984), and a four-volume dictionary of opera (1992).
The second edition under this title (the seventh overall) was published in 2001, in 29 volumes. It was also made available by subscription on the internet in a service called Grove Music Online. It was again edited by Stanley Sadie, and the executive editor was John Tyrrell. It was originally to be released on CD-ROM as well, but this plan was dropped. As Sadie writes in the preface, "The biggest single expansion in the present edition has been in the coverage of 20th-century composers".
This edition has been subject to negative criticism (e.g. in Private Eye) owing to the significant number of typographical and factual errors that it contains. Two volumes were re-issued in corrected versions, however, after production errors originally caused the omission of sections of Igor Stravinsky's worklist and Richard Wagner's bibliography.
Publication of the second edition of The New Grove was accompanied by a Web-based version, Grove Music Online. It too, attracted some initial criticism, for example for the way in which images were not incorporated into the text but kept separate.
Currently, the complete text of The New Grove is available to subscribers to the online service Grove Music Online. Grove Music Online includes a large number of revisions and additions of new articles. In addition to the 29 volumes of The New Grove second edition, Grove Music Online incorporates the four-volume New Grove Dictionary of Opera (ed. Stanley Sadie, 1992) and the three-volume New Grove Dictionary of Jazz, second edition (ed. Barry Kernfeld, 2002), The Grove Dictionary of American Music and The Grove Dictionary of Musical Instruments, comprising a total of more than 50,000 articles. The current editor-in-chief of Grove Music, the name given to the complete slate of print and online resources that encompass the Grove brand, is University of Pittsburgh professor Deane Root. He assumed the editorship in 2009.
The dictionary, originally published by Macmillan, was sold in 2004 to Oxford University Press. Since 2008 Grove Music Online has served as a cornerstone of Oxford University Press's larger online research tool Oxford Music Online, which remains a subscription-based service. As well as being available to individual and educational subscribers, it is available for use at many public and university libraries worldwide, through institutional subscriptions.
Grove Music Online identifies itself as the Eighth Edition of the overall work.
The New Grove is often the first source that English-speaking musicologists use when beginning research or seeking information on most musical topics. Its scope and extensive bibliographies make it exceedingly valuable to any scholar with a grasp of the English language.
The companion four-volume series, New Grove Dictionary of Opera, is the main reference work in English on the subject of opera.
Its principal competitor is the Musik in Geschichte und Gegenwart ("MGG"), currently ten volumes on musical subjects and seventeen on biographies of musicians, written in German.
The 2001 edition contains:
Two non-existent composers have appeared in the work:
Dag Henrik Esrum-Hellerup was the subject of a hoax entry in the 1980 New Grove. Esrum-Hellerup's surname derives from a Danish village and a suburb of Copenhagen. The writer of the entry was Robert Layton. Though successfully introduced into the encyclopaedia, Esrum-Hellerup appeared in the first printing only: soon exposed as a hoax, the entry was removed and the space filled with an illustration. In 1983, the Danish organist Henry Palsmar founded an amateur choir, the Esrum-Hellerup Choir, along with several former pupils of the Song School, St. Annae Gymnasium in Copenhagen.
Guglielmo Baldini was the name of a non-existent composer who was the subject of a hoax entry in the 1980 edition. Unlike Esrum-Hellerup, Baldini was not a modern creation: his name and biography were in fact created almost a century earlier by the renowned German musicologist Hugo Riemann. The New Grove entry on Baldini was supported by a fictional reference in the form of an article supposedly in the Archiv für Freiburger Diözesan Geschichte. Though successfully introduced into the encyclopaedia, Baldini appeared in the first printing only: soon exposed as a hoax, the entry was removed.
Seven parody entries, written by contributors to the 1980 edition, and full of musical puns and dictionary in-jokes, were published in the February 1981 issue of The Musical Times (which was also edited by Stanley Sadie at the time). These entries never appeared in the dictionary itself and are:
