Designed for use by serials librarians concerned with the implementation of OCLC (Ohio College Library Center) in their individual libraries, librarians responsible for deciding to adopt OCLC rather than a competitive system or to add the Serials Subsystem to the services they already receive from OCLC, and information scientists and systems analysts who need feedback from the operational data of their designs in order to test or modify them, this paper briefly reviews the use of OCLC for serials control. Sources cited include evaluative studies, factual material written by OCLC, and case studies of libraries using the system. Problems encountered with the system are discussed. Appendices provide an OCLC chronology a bibliography of case studies of OCLC users, and a sample OCLC check-in record of a serial. (Author/JD)
