13. Authority records
The most common way of enforcing authority control in a bibliographic catalog is to set up a separate index of authority records, which relates to and governs the headings used in the main catalog. This separate index is often referred to as an "authority file." It contains an indexable record of all decisions made by catalogers in a given library (or -- as is increasingly the case -- cataloguing consortium), which catalogers consult when making, or revising, decisions about headings.

24. Precision vs. Recall
Use of subject headings makes a search more precise but limits recall
Use of free text terms and general searches such as in Google enhance recall but limit precision
Libraries typically value precision over recall

RLG
WLN
OCLC
The Research Libraries Group (RLG) was a U.S.-based library consortium which 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 motivation for RLG’s establishment was dissatisfaction among research institutions with OCLC’s record keeping.
