This 1987-88 edition of Association of College and Research Libraries (ACRL) statistics presents data from 100 U.S. and Canadian libraries that are not members of the Association of Research Libraries (ARL), and are not covered by the annual ARL statistics. The 129 non-ARL libraries that were surveyed for this report were classified by the revised Carnegie classification as "Research Universities" I and II and "Doctorate-granting Universities" I and II. Several libraries that had contributed data to previous editions were also asked to participate. The data in this report are based on responses from 101 libraries. For the 70 libraries that had contributed data both in 1978-79 and 1987-88, total expenditures more than doubled during the 9 years between surveys, i.e., from more than $1.8 million to almost $3.8 million. In spite of an increase of 115% in materials expenditures (excluding serials), the libraries had a decline of 1% in the number of volumes added. An increase in the serials budget of 170% at these libraries has resulted in an increase in current serials received only 9%. The number of new employees increased by 10.7%, and their salaries increased by 92% while the Consumer Price Index increased by 70%. The data are organized into 17 charts ranking the order of each of the participating libraries for materials and collections (volumes, serials, microform); salaries and other operating expenses; circulation; and number of library personnel.
