This March 1973 survey assessed library use by non-affiliated users by type of library in the six county library council region. Among the items on the questionnaire distributed to over 100 public, academic, school, and special libraries were: (1) the purpose of the library visit and the subject matter of interest, (2) satisfaction with services provided, and (3) why the particular library was selected including such factors as convenient location, parking, hours of operation, librarian qualities, and the collection. The report indicates that non-affiliated persons utilize public libraries significantly more than other library types, primarily because of the convenience. Therefore, the main element of a successful cooperative venture should be the public library system. Appended are a sample questionnaire and tables. (Author/STS)
