Thirteen of the chapters that comprise the contents of this first volume of Native Languages of the A mericas were originally commissioned by the undersigned in his capacity as Editor of the fourteen volume series (1963-1976), Current Trends in Linguistics. All appeared, in 1973, under Part Three of the quadripartite Vol. 10, subtitled Linguistics in North America. Two additional chaplers are being held over for the volume to follow shortly, devoted to Central and South American lan­ guages and linguistics, where they more appropriately belong. A fourteenth chapter, on the" Historiography of native North A merican linguistics," was written similarly by invitation, for Vol. 13, subtitled Historiography of Linguistics, published in 1975. Both Volumes 10 and 13 were jointly financed by the United States National Science Foundation and National Endowment for the Humanities, with an enhancing contribution to the former by the Canada Council. The generosity of these funding agencies was, of course, previously acknowledged in my respective Editor's Introductions to the two books mentioned, but cannot be repeated too often: without their welcome and timely assistance, the global project could scarcely have been realized on so comprehensive a scale. The Current Trends in Linguistics series was a long-term venture of Mouton Publishers, of The Hague, under the imaginative in-house direction of Peter de Rid­ der. Various spin-offs were foreseen, and some of them happily realized.
