The publishing history of the eleven chapters that comprise the contents of this second volume of Native Languages of the Americas is rather different from that of the thirteen that appeared in Volume I of this twin set late last year. Original ver­ sions of five articles, respectively, by Barthel, Grimes, Longacre, Mayers, and Suarez, were first published in Part II of Current Trends in Linguistics, Vol. 4, subtitled lbero-A merican and Caribbean Linguistics (1968), having been com­ missioned by the undersigned in his capacity as editor of the fourteen volume series which was distributed in twenty-one tomes between 1963 and 1976. McClaran's article is reprinted from Part III of Vol. 10. Linguistics in North America (1973) and the two by Kaufman and Rensch were in Part I I of Vol. 11, Diachronic, A real. and Typological Linguistics (1973 ). There are three contributions by Landar: earlier versions of two appeared in Vol. 10 ("North American Indian Languages. " accompanied by William Sorsby's maps of tribal groups of North and Central America), and in Vol. 13, Historiography of Linguistics (1975); however, his checklist of South and Central American Indian languages was freshly compiled for this book. Generous financial support for preparing the materials included in this project came from several agencies of the United States government, to wit: the National Endowment for the Humanities and the National Science Foundation, for Vols. 10 and 13, and the Office of Education, for Vols. 4 and 11; in addition.
