This project proposed to develop and test the use of microform catalogs produced from computer-generated magnetic tape records in both fiche and film formats. The Computer Output Microform (COM) catalog developed for this purpose is a union list of titles from the five participating libraries--Houston and Dallas Public Libraries, Texas State Library, Waco-McLennan County Library, and Stephen F. Austin University Library. The project was divided into four phases: (1) conversion of data to machine-readable form; (2) microform catalog production; (3) catalog test; and (4) project evaluation. The following activities were documented: (1) vendor selection process and results; (2) production procedures and cost statistics for preparation of machine-readable bibliographic data using the OCLC system; (3) library staff and library user acceptance of the catalog formats; and (4) microform copies of the union catalog. The eight appendices include Input and Edit Procedures, Request for Proposal to COM Vendors, Analysis of Vendor's Bids, Sample Questionnaire (user), and the project Interviewer's Manual. (Author/JAB)
