In Pennsylvania 375 public, academic, and special libraries were surveyed in an effort to gather information concerning their interlibrary loan activity during April, 1978; personal discussions with librarians across the state were also conducted. Both sources were used in the development of recommendations for improving bibliographic access. The results from the 254 libraries that responded, which consisted of a representative cross-section of types, showed that (1) the fill rate for interlibrary loan is over 70 percent; (2) the main reason for not filling requests was that the library did not own the item; (3) over 85 percent of borrowing and lending was in-state; (4) monographs predominated over periodicals; (5) 50 percent of the activity concerned demand for material published since 1972; (6) OCLC is heavily used for bibliographic verification and as a location tool; and (7) in-state, IDS is the predominant form of delivery. Implications of the survey and the discussions with librarians led to the recommendations to develop a coordinated plan to expand access to older bibliographic records within Pennsylvania, including retrospective inputs into the OCLC data base by a greater number of libraries and the creation of a state-wide, online union list of serials; to provide incentives for libraries to share their collections; and to encourage existing agencies that produce indexes to subject collections in Pennsylvania libraries to adopt compatible formats and terminologies.
