Statistical Trends

The following links contain recently published graphs of some of the most interesting trends emerging from data collected as part of the Statistics & Assessment program:

ARL Statistics 2011-12 includes data that describe collections, staffing, expenditures, and service activities for the 125 members of the Association of Research Libraries (ARL). Of these, 115 are university libraries; the remaining 10 are public, governmental, and nonprofit research libraries. ARL member libraries are the largest research libraries in North America, representing 17 Canadian and 108 U.S. research institutions. The academic libraries, which comprise 92% of the membership, include 16 Canadian and 99 U.S. libraries.

The questions and definitions in the 2011-12 ARL Statistics Survey were revised and modernized after an extensive review process led by the Task Force on Reviewing the ARL Statistics, the ARL Annual Salary Survey and the ARL Supplementary Statistics. Members of the ARL Statistics and Assessment Committee and the task force interviewed ARL Directors during the Spring of 2011 and collected feedback that helped them articulate the key issues, questions and revisions for annual data collection purposes. This feedback was shared with ARL Library Directors and Salary Survey contacts, and the final list of job categories was approved by the ARL Board in April of 2011. Please see the revised questions and instructions on the 2011-12 ARL Statistics mailing web page for more details about the revisions.
