    Abstract
    Reports results of research to examine users conducting their initial online search on a particular information problem. Findings from 3 separate studies of relevance judgements by 44 initial search users were examined, including 2 studies of 13 end users and a study of 18 user engaged in mediated online searches. Number of items was judged on the scale 'relevant', 'patially relevant' and 'not rlevant'. Results suggest that: a relationship exists between partially rlevant items retrieved anch changes in the users' information problem or question during an information seeking process; partial relevance judgements play an important role for users in the early stages of seeking information on a particular information problem; and 'highly' relevant items may or may not be the only items useful at the early stages of users' information seeking processes
