    Abstract
    Reports of a study in a Chilean university library, comparing 100 users of online databases and CD-ROMs with 100 users of non-computerized bibliographical resources. Results showed that users tended to be teachers / researchers, and potential users were postgraduate students. Comparison of search results showed online searching improved results and saved time. The chief reasons for non-use were ignorance of the service and use of own personal computer. The study indicated the need to review policy on database acquisition and improve promotion of the service. In general, librarians should motivate greater use of online searching by providing skilled intermediary services to maximize uptake
