Title
Mental models theory and search outcome in a bibliographic retrieval system

Abstract
Reports on a study which examined the relationship between the end user's mental model of a bibliographic retrieval system and search outcome. Interviews were conducted to determine level of complete, good, incomplete and poor mental models. Subjects conducted a predetermined set of searches using a bibliographic retrieval system. A record of each search was kept and used to examine search outcome. Results supported the hypothesis that there is a relationship between the completeness of the end user's mental model and both error behaviour and total number of successful searches
