This is the annual bibliography of 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 more than 45 years (the first two volumes, covering the years 1939-1947, were published in 1949-1950), "Bibliographie Linguistique" provides a comprehensive bibliography in the field. It covers all branches of linguistics and related disciplines, both theoretical and descriptive, from all geographical areas, including less known and extinct languages, with particular attention to the many endangered languages of the world. Up-to-date information is guaranteed by the collaboration of some 50 contributing specialists from all over the world.
