Research Libraries Group
（重定向自Research Library Group）
The Research Libraries Group (RLG) was a U.S.-based library consortium. They developed the Eureka interlibrary search engine, the RedLightGreen database of bibliographic descriptions, and ArchiveGrid, a database containing descriptions of archival collections. RLG was founded by a group of major research libraries in 1974, two years after OCLC, another library consortium, was founded. A major reason for RLG’s establishment was dissatisfaction among research institutions with OCLC’s record keeping.
