    Abstract
    Discusses the 5 fundamental concepts of information retrieval addressed by Patrick Wilson - information, aboutness, relevance, need and use. Although it is impossible to reach consensus definitions for these concepts it can be helpful for future discussions in information retrieval researches

    Abstract
    Uses an information processing approach to analyse the behaviour of end users in searching online bibliographic databases, with particular emphasis on errors made. Following instruction in online searching, 41 students and 3 faculty end users conducted 79 subject searches. Analysis of search transcripts identified 119 reasons for errors. Errors occured most frequently in connection with functions, moves, and elements of 'create and develop sets' and 'display and print records'. Surprisingly, the results do not indicate that end users make errors less frequently as they gain more experience and practice, although syntax-related errors do decrease with time

    Abstract
    Identifies 6 types of searches on the basis of paudsing behaviour by using cluster analysis. The 6 types of search were highly associated with search fleuncy and the construction of a mental model. Examines learning during multiple searches on the basis of the 6 types. Finds that searchers gain more experience, increase their searching proficiency and become more fluent at searching while online. The changes of search level in multiple searches showed that most searchers moved towards greater fleuncy

    Abstract
    Attempts to investigate situational variables which can affect the results of relevance judgements, including computer experience, search experience, familiarity with search topic, preparation time, research objecttives, and research stages. The results show only the search experience will affect relevance judgements. Concerning research objectives, students writing term papers yield less relevance odds but a higher precision rate. concerning research stage, searchers in the early research stage yield more relevance odds and a higher precision rate
