RIPM (Le Répertoire International de la Presse Musicale) is widely regarded as the most comprehensive resource offering electronic access to music periodicals from the early Romantic era to the twentieth century. Founded in 1980 by H. Robert Cohen, RIPM is the youngest of the so-called ‘4 R's of International Music Research’; its partner initiatives include RISM (Répertoire International des Sources Musicales), RILM (Répertoire International de Littérature Musicale), and RIdIM (Répertoire International d'Iconographie Musicale). Cohen's ambitious project was notably visionary in its use of technology: not only did it use computing from the start (beginning with DOS-based indexing systems), but it was also the first of the 4 R's to explore full text searching. RIPM seeks to address ‘two main problems that have prevented these [historic music] journals from being systematically collected and examined: (1) the limited number of libraries possessing the journals, and (2) the difficulty encountered when one attempts to locate specific information within an available source’. The project has thus focused on collection building, curation, indexing and accessibility. This international cooperative's accomplishments are impressive: as of July 2020, the database contains 527 music periodicals, 430 available in full text complete runs, totalling 996,000 annotated records and 1.47 million full-text pages of music periodicals.

RIPM（Le Répertoire International de la Presse Musicale）被广泛认为是最全面的资源，提供从早期浪漫主义时代到二十世纪的音乐期刊的电子访问。RIPM 由 H. Robert Cohen 于 1980 年创立，是所谓的“国际音乐研究 4 R”中最年轻的一个。其合作伙伴计划包括 RISM（Répertoire International des Sources Musicales）、RILM（Répertoire International de Littérature Musicale）和 RIdIM（Répertoire International d'Iconographie Musicale）。Cohen 的雄心勃勃的项目在技术的使用方面具有明显的远见：它不仅从一开始就使用计算（从基于 DOS 的索引系统开始），而且它也是探索全文搜索的 4 R 中的第一个。RIPM 试图解决“阻碍这些 [历史音乐] 期刊被系统收集和审查的两个主要问题：（1）拥有这些期刊的图书馆数量有限，以及（2）在试图找到特定信息时遇到的困难”在可用的来源内”。因此，该项目专注于馆藏建设、管理、索引和可访问性。这个国际合作的成就令人瞩目：截至 2020 年 7 月，该数据库包含 527 种音乐期刊，430 种可全文完整运行，总计 996 种，
