One mainstay of the Boasian tradition in anthropological linguistics is the notion that adequate documentation of a language must consist of at least three volumes: a grammar, a dictionary, and a collection of texts. This convention grew out of Boas's dogged insistence on the collection of copious texts in the native languages as a way of documenting the cultures of Native North Americans, which he believed were breaking down and disappearing. Obviously, if one were actually to make use of such texts, a grammar and a dictionary were also needed; so this practice of a necessary trilogy was established, a tradition that has continued in academic departments which carry on the Boasian heritage (illustrated by the postgraduate work and resulting publications of the editor of this journal).
