This self-study was initiated at the Columbia University Libraries (CUL) to establish the foundations and appropriate mechanisms for the future planning, development, and implementation of public services at CUL. Following completion of an inventory and an interim report, which include background data on CUL, Columbia University, research libraries, and professional trends, five task forces were established to study the following concerns: (1) articulating public services; (2) evaluating the impact on services of CUL's participation in cooperative arrangements; (3) technology and public services; (4) the effect of interdepartmental relationships on services; and (5) the university library user community. An introduction, executive summary, and discussion of the study background and methodology are followed by reports and recommendations of each task force. Based on the planning assumptions enumerated in this report, the study team's major findings and recommendations are organized as follows: Planning; Reference and Other Public Services; Communications; Staff Training and Development; Collection Development and Management; and Physical Facilities and Space Planning. A consolidated list of recommendations concludes the final report. Task force members and charges, an index to information gathered during the study, and a glossary of acronyms are appended. (THC)
