Book excerpt: The works of Edward Sapir (1884 - 1939) continue to provide inspiration to all interested in the study of human language. Since most of his published works are relatively inaccessible, and valuable unpublished material has been found, the preparation of a complete edition of all his published and unpublished works was long overdue. The wide range of Sapir's scholarship as well as the amount of work necessary to put the unpublished manuscripts into publishable form pose unique challenges for the editors. Many scholars from a variety of fields as well as American Indian language specialists are providing significant assistance in the making of this multi-volume series.
