This fifth and final report describes activities since June, 1965. Centralization of the Eisenhower Library Collection was completed early in 1965 and a circulation system became operational in April, 1965. The main portion of this report focuses on various aspects of the circulation system such as preparation of identification cards; the photographic process; circulation control operations (date due stickers, key punching and verifying, library utilization, work in process delay, quality control, and computer operations); and a simulated borrowing study. It is proposed in the report that an all-numeric code replace the call number or input identifier in the circulation system. The processing and updating procedures for the shelf list on tape are described. Acquisitions, cataloging, and activities of the library staff are discussed briefly. (CC)
