Abstract

This research investigated the ways in which different levels of knowledge about a topic can affect searching for information on that topic in a library online catalog. It was found that people with high levels of knowledge use more search expressions, including more general and nonproductive expressions, than low-knowledge users. It was also found that high-knowledge users employed more search expressions that had not been contained in their statements of information need than low-knowledge users. These differences in vocabulary use and search expression formulation may be of interest to designers of online catalogs as they attempt to increase the responsiveness of catalog systems to the needs of individual users

Abstract

Browse searching of online catalogs and electronic indexes is a popular means of retrieving information, but some subject heading lists are so extensive that browsing them can be difficult and time-consuming. This resaerch tested one way of presenting a browse interface to reduce the amount of scanning of subject headings required. It found that a hierarchical presentation of headings reduced the amount of scanning required by more than 50% without any reduction in the effectiveness of the search. Better browsable displays of this sort can improve the efficiency of searching but appear not to alter effectivenenss

Abstract

"Librarians should be careful to distinguish between their own abilities and those of their patrons when designing information systems, bibliographic instruction programs, and similar library services. The abilities of professionals may lead to preferences for sophisticated interfaces, complex instructional programs, or services that assumehigh levels of cognitive abilities, while their library patrons may find browse interfaces, simple point-of-need instruction, and basic services to be more appropriate to their levels of cognitive abilities
