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, services, and library and university characteristics.
