"ARL Statistics 1998-99" is the latest in a series of annual publications that describe collections, staffing, expenditures, and service activities for the 121 member libraries of the Association of Research Libraries (ARL). The first section of the report includes several illustrative charts and discusses service trends; the decline of ownership, and monograph and serial costs in ARL libraries (1986-1999); the promise of access, and supply and demand in ARL libraries (1986-1999); expenditure trends in ARL libraries (1986-1999); and resources per student in ARL libraries (1986-1999). The body of the publication consists of ARL library data tables for 1998-99 that provide statistics and summary data on collections, expenditures, and personnel and public services. An analysis of selected variables of ARL university libraries for 1998-99 and Ph.D., faculty, and enrollment statistics are given, followed by rank order tables of university libraries for 1998-99. The ARL Statistics Questionnaire, footnotes to the ARL statistics, and a list of ARL member libraries are included at the end of the document. (Contains 75 references.) (AEF)
