摘要:THE interlibrary loan staff of the University of Cincinnati Medical Center Libraries is dedicated to providing prompt service to its requesters. It appeared from checking books loaned to other libraries that a considerable length of time was required for shipping those materials. Occasional communications from other libraries concerning the delayed receipt of books reemphasized the time spent in transit; for example, a book was received after the loan period expired, and the time in transit was three weeks for an approximate two-hundred-fifty-mile distance. At the same time the interlibrary loan staff observed from checking materials borrowed from Library A that their use of United Parcel Service (UPS) provided more rapid service.
