Répertoire international de la presse musicale (Retrospective Index to Music Periodicals, Internationales Repertorium der Musikzeitungen), commonly known as RIPM, provides access to music periodical literature published between 1750 and 1966 through an annotated index, the RIPM Retrospective Index to Music Periodicals and two full-text publication series, the RIPM Online Archive of Music Periodicals and the RIPM e-Library of Music Periodicals.

Founded in 1980 by H. Robert Cohen with the collaboration of Marcello Conati, Elvidio Surian, and Christoph-Helmut Mahling, RIPM is one of the four Répertoires (or "R" projects) established by the International Musicological Society (IMS) and the International Association of Music Libraries, Archives, and Documentation Centres (IAML); these include Le Répertoire international des sources musicales (RISM), Le Répertoire international de littérature musicale (RILM), and Le Répertoire international d’iconographie musicale (RIdIM). RIPM was established by these societies to address two problems: (1) the limited availability of the journals themselves, as most are found in very few libraries and in incomplete runs and/or poor physical condition, and (2) the difficulty in accessing content in a journal once a copy has been located.

RIPM profits from a network of scholars, librarians, and archivists in more than 20 countries and maintains an editorial headquarters in Baltimore, Maryland (the RIPM International Center). To collect and complete runs of journals, RIPM works with a network of partner and participating libraries in the United States and Europe. With only rare exceptions, RIPM makes available complete runs of music journals, many of which represent the only complete copy available anywhere.
