Describing and evaluating library collections

Abstract

The importance of the description and evaluation of library collections for entries in library directories (source guides) has been underestimated. The article considers the purposes of characterizations in source guides, and the methods and problems of obtaining the information required. The elements which compose a characterization are discussed: subjects and topics covered; intimation of size; the question of "level"; library policy; comparison and evalua tion. The indexing of directory entries is discussed, and implications suggested for future source guides.
