Interlibrary loan (ILL) transactions are a major library problem because the increased volume places a burden on systems developed with no general plan. This report lists nine difficulties identified by the 1974 National Commission on Libraries and Information Science. Automated networking is imperative for ILL's future. The Ohio College Library Center (OCLC) is an emerging national, nonprofit network, undergoing continual evolution in its data bases, hardware, membership, and development of new subsystems. Its potential services and data base size make libraries eager to join. OCLC serves as an abbreviated National Union Catalog, and most members use the data base for ILL. An ILL subsystem is being developed to solve problems in communications, recordkeeping, bibliographic control, and cost, with six basic capabilities and three files. In the long range it can bridge the gap between network promotion and library education. The role of OCLC could be as chief overseer in planning as part of a larger network, or OCLC could become the major ILL facility in North America, thereby determining the future of librarianship.
