    Abstract
    The authors present a study of the real-life information needs of 59 McGill University undergraduates researching essay topics for either a history or psychology course, interviewed just after they had selected their essay topic. The interview's purpose was to transform the undergraduate's query from general topic terms, based an vague conceptions of their essay topic, to an information need-based query. To chart the transformation, the authors investigate N. J. Belkin, R. N. Oddy, and H. M. Brooks' Anomalous States of Knowledge (ASK) hypothesis (1982a, 1982b), which links the user's ASK to a relevant document set via a common code based an structural facets. In the present study an interoperable structural code based an eight essay styles is created, then notions of structural facets compatible with a highimpact essay structure are presented. The important findings of the study are: (a) the undergraduates' topic statements and terms derived from it do not constitute an effective information need statement because for most of the subjects in the study the topic terms conformed to a low-impact essay style; (b) essay style is an effective interoperable structural code for charting the evolution of the undergraduate's knowledge state from ASK to partial resolution of the ASK in an information need statement.

    Abstract
    In this study, Texas A&M University faculty and graduate students from 16 departments completed a survey about their methods of finding videocassettes in the library, how they searched the online catalog LibCat for videocassettes, and their perceptions of catalog record elements. Results demonstrated that the majority of respondents used LibCat the most often for finding videocassettes. They searched by title and were satisfied with known item searching. Finally, respondents considered authors of original works, actors, and directors as useful to both search and view in LibCat, while few perceived editor, consultant, and camera person as useful.
