    Abstract
    BLAISE-LINE provides online access to all of the British Library's major catalogues as well as to other major bibliographies. With its MARC records, Dewey numbers and Library of Congress headings (LCSH), BLAISE-LINE remains a tradtional library oriented online service. Presents the results of a survey of 37 libraries using BLAISE-LINE to find out what users thought of it and how it compared to the more modern systems of enduser, fulltext, CD-ROM and the Internet. The principal uses to which respondents put BLAISE-LINE were bibliographical checking, answering subject enquiries, and obtaining interlibrary loans. The survey also covered frequency of use, ease of use, problems in using the system, cost issues, and training and support. Findings show that professional librarians value the efficiency of BLAISE-LINE above the user friedliness of other systems
