The result of a year-long study designed to establish a 5-year plan for preserving Northwestern University Library's collections, this report draws on preliminary task force reports to make 14 specific recommendations that will enable the library to meet its preservation challenge. The recommendations are presented in four clusters which address the areas of library material, library buildings, library staff and users, and maintaining innovation and leadership. Strategies for the future are also discussed. In addition, eight attachments provide supplementary imformation. Their titles are as follows: (1) Summary of Recommendations; (2) Extent of the Need for Various Preservation Treatments; (3) Discussion Paper for a Mass Deacidification Facility; (4) Ten- Ten-Year Growth and Allocation of the One Percent Levy for Preservation; (5) Preservation Department Organization Chart; (6) Policy Statement on Preservation Selection; (7) Study Team Discussion Paper on Additional Storage Space for the Collections; and (8) Job Description for the Administrative Assistant for the Preservation Department.
