摘要:IN 1979 THE administration of Tucson Medical Center (TMC) encouraged the library staff to explore the possibility of assisting rural Arizona hospitals in developing medical library services. One of the greatest obstacles encountered in establishing effective rural hospital libraries was the absence of trained reference personnel to provide on-site service. Another considerable problem was the delay in document delivery using normal interlibrary loan techniques. In an effort to improve reference service to rural hospitals, the TMC library staff developed a new on-line computer information retrieval technique, which we have named Simultaneous Remote Search.
