    Abstract
    Reports on research which aims to discover the path patterns through which users retrieve information in hypertext systems. Takes a pragmatic approach in which the use of a hypertext information retrieval system by a group of subjects was monitored to collect path pattern data. Two frequency distribution models were developed and tested using these data. Path length followed a shifted negative minimal distribution. The influence of search tasks on path patterns was examined and found to have no effect. These models can provide a background for examination of systems via stimulation studies

    Abstract
    Reports an experiment conducted to study search behaviour of different user groups in a hypertext information retrieval system. A three-way analysis of variance test was conducted to study the effects of gender, search task, and search experience on search option (analytical searching versus browsing), as measured by the proportion of nodes reached through analytical searching. The search task factor influenced search option in that a general task caused more browsing and specific task more analytical searching. Gender or search experience alone did not affect the search option. These findings are discussed in light of evaluation of existing systems and implications for future design
