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
