A bibliography of 914 numbered items from 21 countries: books, articles, reports, Rand memoranda, and symposium contributions relevant to the fields of computational linguistics and documentation that became available in 1966. Particular attention is given to classification theory and practice and to computer hardware and programming for nonnumerical applications (language processing). Entries under Documentation cover abstracting, bibliographic analysis, dissemination, indexing, organization, personnel, user relations, and publications systems. Psycholinguistics receives extensive coverage. There are also items on research methods, semantics, structural theory, style, and on the characteristics of 17 languages and language groups. An author index and an organization index are included, the latter divided by country. This is the third annual compilation of the monthly lists prepared by the Rand computational linguistics project for [The Finite String] (Association for Machine Translation and Computational Linguistics).
