ARL Statistics® Survey

This survey collects data that describe the collections, overall library expenditures, materials expenditures, staffing, and operational and service activities of member libraries. This data series began in 1908 and represents the oldest and most comprehensive continuing library statistical series in the United States and Canada. Libraries use these data to describe their operations and demonstrate how resources are used wisely for the benefit of the communities they serve. The data is used to produce the ARL Investment Index, a summary measure of relative size among the universities of the Association.

The pre-1962 data is compiled in the Gerould StatisticsPost-1962 survey data is used to produce the ARL Statistics, the ARL Academic Health Sciences Library Statistics, and the ARL Academic Law Library Statistics series. See the Publications & Resources page for more information about these publications.
