History
Statistics have been collected and issued annually for the members of the Association of
Research Libraries since 1961-62. Before that, annual statistics for university
libraries had been collected by James Gerould, first at Minnesota and later at Princeton.
These data cover the years 1907-08 through 1961-62, and are now called the Gerould
statistics. The whole data series from 1908 to the present represents the oldest continuing
library statistical series in North America. The current ARL statistics include data on
collections, staffing, expenditures, library services, and library and university
characteristics.
The Gerould Statistics are now available in a revised edition
here.
For more information on the data made available here or for assistance in interpreting the current data or in ordering
earlier data, contact Martha Kyrillidou (martha@arl.org) at ARL.
A Guide to the Machine-Readable Version of the ARL Statistics is on the ARL site.
