This is the annual bibliography of theoretical linguistics published by the Permanent International Committee of Linguists under the auspices of the International Council of Philosophy and Humanistic Studies of UNESCO. With a tradition of over sixty-five years, the 'Linguistic Bibliography' is by far the most comprehensive bibliographic reference work in the field. It covers all disciplines of theoretical linguistics, both general and language specific, from all geographical areas, including endangered and extinct languages with particular attention to lesser-known Indo-European and non-Indo-European languages. Up-to-date information is guaranteed by the collaboration of some forty-five contributing specialists from all over the world. With over 20,000 titles arranged according to a subject and language classification, the Linguistic Bibliography is a standard reference work for every scholar of language and linguistics. This volume has been brought up-to-date and contains extensive indexes of names, languages, and subjects.
