Analysis of the needs of users of Compact Disk-Read Only Memory (CD-ROM) was performed at the Tampa campus of the University of South Florida. A review of the literature indicated that problems associated with selecting the appropriate database, searching, and requiring technical assistance were the probable areas of user need. The library has 17 databases and uses 9 types of software. Statistics were gathered on 20 different days, typically during the work week. User need was broadly defined as a request for assistance addressed to the CD-ROM assistant, who was also the observer. Of the 487 questions, 134 were technical questions of various types that concerned software or hardware, 115 concerned selecting the appropriate database, and 110 concerned search strategy. The analysis suggests areas in which librarian and patron training would be beneficial. (Contains 12 references.) (SLD)
