RIPM Retrospective Index to Music Periodicals is an international annotated bibliography of writings on musical history and culture, found in music periodicals published in seventeen countries between approximately 1800 and 1950. Treating primary source material, RIPM indexes the content of complete runs of journals, including articles, reviews, news columns, miscellaneous items, surveys of the press, bibliographies, iconography and advertising. In addition, this database offers access to an immense bibliography of music and to thousands of English-language translations of foreign documents. Approximately 20,000 records are added annually. RIPM is produced under the auspices of the International Musicological Society (IMS) and the International Association of Music Libraries, Archives and Documentation Centres (IAML).
