    Abstract
    The results of 35 searches performed by users (end users) of an academic library (Illinois Stae University, Milner Library) in the ERIC databases on CD-ROM were compared with the results for the same topics achieved by an experienced education librarian and by a team of librarians. Recall ratios, precision ratios, and novelty ratios were calculated. Results show that the users, all faculty members or graduate students, found only about a third of the really important items. Suggests that library users are frequently misled into thinking that CD-ROM databases are easy to use and that the 'technology' guarantees satisfactory results.
