On types of search and the allocation of library resources

Abstract

Abstract This article discusses the different types of searches made in libraries in two ways. In Part I a review of some examples of searches leads to the conclusion that the traditional dichotomy of “known item” and “subject search” is inadequate. A more satisfactory method would be to regard every search as being for both (more or less) specified documents and (more or less) specified “subjects.” Part II considers the allocation of library resources in relation to patterns of searches. The literature of user studies reveals significant variations in the nature of searches in different groups of users. Alternative allocations of library resources and choices concerning library technology vary considerably with respect to the cost effectiveness of the resulting service in meeting demands upon it. Viewing libraries from this perspective provides an explanation and rationalization of the distinctive features of different types of library: public, academic, and special.
