    Abstract
    Bibliographic searching usually involves finding documents which fulfil already specified search criteria, but Swanson has attempted to develop methods described as a systematic trial and error stzrategy, to find unknown causal scientific connections between already known phenomena, so-called undiscoverd public knowledge, or complementary but disjoint literatures. To this end he conducted 3 investigations in biomedicine. While specialist knowlegde is needed to find the literature linking the literature of problems with that of the solutions, Swanson hopes to make the method more automatic. Clinical trials seem to support his hypothesis

    Abstract
    Report on the conference on Information Authority and user knowledge held in Boras Apr 93 and arranged by Gothenburg University's Centre for Library and Information Science and Studies and Boras Library High School. The main speaker, Patrick Wilson, spoke on consequences of information overload and rapid conceptual change. Johan Olaisen's talk on 'toward a theory of clarified subjectivity' started like Wilson's with the problem that users of information systems drown in trivialities. Lena Olsson's dealt with library work in practice and commented on the connection between cognitive authority and professional status of librarians. Discussions centered on the definition of information authority, and on overload as the driving force in IF development

    Abstract
    Examines how far automation cluster analysis and association testing are relevant methods for smaller libraries in construction of search thesauri. Using WORDSTAR, a simple form of cluster analysis was tested, with satisfactory results in that the index terms formed clusters of a suitable size. The association test was used to elicit from users' natural language terms which can be used in the search thesaurus as entrance vocabulary. The test showed that users associated very differently in relation to the same stimuli words, with low overlap with terms used in the system's indexing. The results confirmed the need for better feedback. Concludes that while neither method can be used alone, a search thesauri which combine terms from the indexes and from users can be a powerful tool
