This report outlines the development of the Ohio College Library Center (OCLC) and considers some basic problems in OCLC shared cataloging--e.g., the uneven quality of input cataloging and increasing number of duplicate records. Summaries of findings from an OCLC evaluative study and two surveys of shared cataloging are presented. The report points out that administrators should consider cost and computer compatibility before joining OCLC, and notes the challenge for librarians to make the most efficient and effective use of the system. A bibliography of 34 articles, videotapes, papers, manuals, books, and annual reports on OCLC is attached. (KP)
