    Abstract
    Presents the design of a prototype adaptive online catalogue. Online catalogue searches commonly retrieve too few or too many items. The prototype, implemented as a transparent workstation based front end to a MELVYL online catalogue of the holdings of the 9 campuses of California Universities, adapts to excessive or insufficient retrieval by strategically limiting, sorting or expanding users' searches, based on preferences defined by the user
