    Abstract
    Shortened and revised version of a paper presented during an Education Librarian's Group session at the Under One Umbrella Two Conference, organized by the Library Association in Manchester, 9-11 Jul 93. With the possibility of free text searching and easy access to CD-ROM databases, users often do not realise that subject searching is enhanced by familiarity with the controlled vocabulary underlying the indexing system of the database. Discusses the construction of information retrieval thesauri, the problems of terminology and how the use of thesauri can make searching more effective, using education thesauri as examples

    Abstract
    Studies of indexing neglect the first stage of the process, that is, subject analysis. In this study, novice indexers were asked to analyse three short, popular journal articles; to express the general subject as well as the primary and secondary topics in natural laguage statements; to state what influenced the analysis and to comment on the ease or difficulty of this process. The factors which influenced the process were: the subject discipline concerned, factual vs. subjective nature of the text, complexity of the subject, clarity of text, possible support offered by bibliographic apparatus such as title, etc. The findings showed that with the social science and science texts, the general subject could be determined with ease, while this was more difficult with the humanities text. Clear evidence emerged of the importance of bibliographical apparatus in defining the general subject. There was varying difficulty in determining the primary and secondarx topics

    Abstract
    Reports results of a study which applied a typological procedure, developed by Lazairsfeld from the social sciences, to a set of qualitative data on fiction reading habits for the purpose of forming a practical typology of fiction borrowers. The data was collected from a sample of 300 readers in 2 medium sized UK public libraries over a 2 month period. The procedure, using an inductive research approach, first mapped readers along 6 dimensions of reading habits which emerged from the data frequencies of borrowing, the numbers of authors currently read, the literary/recreational orientation of reading, searching approaches usually applied, sureness (confidence) in book selection and then proceeded to reduce the number of combinations formed by these dimensions, based on their relationships. A typology of 7 types of fiction borrowers was devised: readers of particularism; readers of frequent literary pluralism; readers of infrequent literary pluralism; readers of frequent recreational pluralism; readers of infrequent recreational pluralism; readers of frequent universalism; and readers of infrequent universalism

    Abstract
    The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user
