The projects reviewed in this annual report of the Online Computer Library Center, Inc. (OCLC) focus on four strategic areas: (1) enhancing the use of the OCLC Online Union Catalog; (2) investigating full document storage, retrieval, and presentation; (3) strengthening the interface between patron and system; and (4) providing statistical information for improved database management. Introductory materials include brief statements by individual members of the research advisory committee and an overview of the OCLC research program. This overview briefly describes the activities in each of the four strategic areas and how they contribute to the OCLC mission. Individual reports are then presented for the following: 17 OCLC projects; 6 external and collaborative research projects; and 7 library and information science research grant program projects. Abstracts of seven presentations in the distinguished seminar series are also provided. The report concludes with descriptions of research programs sponsored by OCLC, i.e., the visiting scholar program, postdoctoral fellowships, and research assistants program; biographical sketches of OCLC staff; an annotated listing of some other OCLC publications; and a prepaid reader survey card.
