    Abstract
    Recent research shows that users of online catalogs find subject searching difficult, that characteristics of subject searches are qualitatively different from those of known-item searches, and that some design features of online catalogs appear to perform better than others for topical searching. It has been recommended that system designers develop different approaches, or interfaces, for different kinds of searching. This paper revies available design techniques from a subject searching perspective, including various methods of indexing bibliographic records, processing and correcting user input, searching the database, and displaying search results. The review concludes that there are many alternative approaches, each with strenghts and weaknesses, and combining techniques in new ways may have unknown results, but many promising methods are nonetheless available now to make more effective use of the subject information in current bibliographic records.
