Abstract

In pt.1, argued that modern classification theory and philosophy of science can help us understand problems of searching. In pt.2, discusses the problems in a more technical sense. considers thesauri and studies of of concept formation: choice of subject headings; definitions, and associations between subject headings; and the librarian as intermediary between the users and the library's texts. Tests the hypothesis that a catalogue record can be improved by adding information which makes the record more precise. If a record clearly indicates that a book is a typical or non-typical book on a subject, no improvement is necessary. discusses how and what new information to add and psychological barriers to this
