Summary or Abstract : One of the most challenging problems in the field of information science is developing effective retrieval interfaces for digital libraries. Solutions to this problem must provide interfaces that mediate between the retrieval needs of library users and any available collection materials in an intelligent and tractable manner. The majority of research in this area has focused on the development of information retrieval systems that attempt to match users textual queries to library records. An alternative approach is to build retrieval interfaces that allow users to direct their own searches by browsing through an organization of a library's materials. This dissertation specifies the design characteristics of browsing-based retrieval interfaces for digital libraries. This design has been implemented in Dفjظ vu, a computer program that solves the retrieval problem in the following ways. First, rather than browsing through library materials directly, users of Dفjظ vu browse through an organization of the thesaurus terms that library archivists have used to index collection materials. Second, a tight integration between thesaurus terms and library records allows Dفjظ vu to provide information about the availability of materials in a collection throughout the browsing process. Third, Dفjظ vu provides a rich browsing space to users by utilizing new knowledge structures called Expectation Packages. Expectation Packages cluster sets of terms from a thesaurus into fully interconnected groups, forming simplified cognitive science knowledge representations. By creating a set of these Expectation Packages for a particular thesaurus, developers can efficiently create a rich browsing space that reflects the knowledge that is common to the intended users of a digital library. A full set of Expectation Packages were developed for one thesaurus which is used by many photographic libraries. Dفjظ vu was then evaluated in the context of its use as a retrieval interface for large digital collections..
