    Abstract
    Explores inter record linkage relationships of a bibliographic hypertext system through the use of descriptor term co-occurrences. Using term distribution and term exhaustivity data for an existing system, develops 3 models of term co-occurrence and tests against the observed data. The developed models do not adequately model the observed co-occurrence patterns for select parts of the distribution using chi-square values. With knowledge of the structure of such a hypertext system, an appropriate model may be constructed and used as the basis for studying systems design of inter-record linkages and system navigation by users in such a hypertext system

    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
