Choguita Rarámuri (Tarahumara) is a Uto-Aztecan language spoken in Northern Mexico of great typological, theoretical, and historical significance. This paper presents an overview and background of the Choguita Rarámuri language description and documentation project and provides a guide to the documentary collection emerging from this project. This collection, deposited in the Endangered Languages Archive, is the result of collaboration with community members with the long-term goals of aiding in language preservation efforts and the development of a reference grammar of the language. While the production of linguistic analysis in the form of the reference grammar and other publications motivates a significant amount of the documentary corpus, the collection was also theorized from the perspective of a variety of audiences and provides an example of community-based design of documentary materials. This paper provides details on the development of the project, which allows readers to contextualize the scope and nature of the resulting corpus. This paper also discusses current restrictions on access to the collection, as well as an overview of existing associated materials and work underway that seeks to provide direct links between the deposited collection and products of linguistic analysis.
