This report is the result of a meeting to consider the need for broad assessment of the fundamental changes in library and information services needed to keep pace with the electronic age. Participants agreed to plan for the establishment of an annual series of policy forum meetings for participants from a variety of disciplines to consider issues and developments in library and information services data needs. The forum focused on four papers addressing critical issues facing library and information services: (1) "Measuring the Impact of Technology on Libraries" (Martin Dillon); (2) "Multitype Library Collaboration: Measures of Implicit Impact" (Mary Treacy Birmingham); (3) "Information To Enhance Planning for Education for Library and Information Services Professionals: What Do We Need To Know?" (June Lester); and (4) "Statistical Support for Urban Library Services" (Eleanor Jo Rodger). Two appendices present a news release about the forum and an excerpt from "Libraries at Large," a 1969 publication of the Federal Institute of Library and Information Science. (SLD)
