This paper presents results from a study undertaken in 1983 at the Australian National University (ANU) to determine the extent and type of problems academic staff and students had while using the library's catalogs or while locating materials on the shelves. A questionnaire mailed to a stratified random sample of approximately 1,200 academic staff, post-graduate and undergraduate students, and research assistants, yielded a response rate of between 70% and 87% for each of the target populations. Responses showed that a substantial portion of the university community had experienced some or all of the following: (1) confusion resulting from the number of different catalog sequences and the variety of formats used on microfiche and card records; (2) inadequate sign postings and floor plans; (3) insufficient reader service instruction on the range of library materials available and its location; and (4) inadequate information about changes in the catalog or relocation of particular books and journals. Information was also obtained on the desired range of access points to be made available when the catalog is put online. Tables displaying survey results and the nine-page survey questionnaire are included. (THC)
