This document examines the changes in organization and staffing of preservation programs since SPEC (the Systems and Procedures Exchange Center) surveyed members of the Association of Research Libraries (ARL) in 1985. It is based on responses of 109 ARL libraries to ARL preservation surveys, and additional contacts with 21 ARL libraries that have established major preservation programs. An introductory overview discusses the survey responses in the context of five trends: (1) institutionalization of preservation activities; (2) continuing changes in the organization and staffing of preservation programs; (3) significant growth in the size of preservation programs; (4) growing emphasis on broad administrative and managerial responsibilities; and (5) increased specialization in preservation positions. A compilation of preservation statistics is also provided. The major part of the document is made up of materials submitted by respondents; i.e., organization charts, position descriptions, and/or planning documents from Brown University; University of California at Berkeley; Case Western Reserve University; University of Chicago; Columbia University; University of Connecticut; Duke University; McGill University; National Library of Medicine; Northwestern University; Ohio State University; Oklahoma State University; Smithsonian Institution; University of Southern California; Southern Illinois University; University of Toronto; and Vanderbilt University.
