Three aspects of information work in libraries, archives, museums and community information services are covered: the way in which information is controlled so that it can be retrieved; the bibliographies which provide this control; and the sources in which the information can be located. Bibliographies (ranging from catalogues to national bibliographies) and content sources (ranging from encyclopaedias to patents) are studied in all their forms: printed, microform and online databases, including CD-ROM. The book is specifically attuned to southern Africa. Although it is designed for students of information science and applied information science (librarianship), it also provides an effective guide to major South African and international reference and information sources.
