    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

    Abstract
    Reports on research examining the relationship of searcher performance and perception of performance, particulary for hypertext-based onformation retrieval systems for bibliographic data. Employs a prototype hypertext bibliographic retrieval system called HyperLynx. Evaluates its use by 83 subjects at the School of Library and Information Science and the Golda Meir Library at the University of Wisconsin-Milwaukee, USA. Measures of system usgae indicate that there is no significant relationship between confidence and the number of record pages visited, although confident searchers searched for shorter time periods. The reality check measures shows that both novice and experienced searchers were over confident in their performance
