The monumental 696-page Barona Inter-Tribal Dictionary was presented to the National Museum of the American Indian (NMAI) and to the Bureau of Indian Affairs (BIA) during Native American Heritage Month
. The dictionary is comprised of thousands of familiar as well as long-lost words and phrases aimed at assisting Yuman language speakers of the San Diego County Tribes in revitalizing their traditional native tongue.
A revised and enhanced version of the original 48-page Barona dictionary project, the expansive and updated edition contains a number of innovative features such as history of the project, biographies of the main contributors and a map of the language area.
