This source book provides information on school, college, and community programs that teach American Indian languages in Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. These programs were identified through leads provided by a nine-member regional task force of Native educators and language activists; consultation with federal and state agencies; information requests on listservs; and a survey of likely organizations, tribes, and other contacts. The source book begins with a brief overview of the status of Native languages in the five-state region and a description of the source book's development and the data collection methods used. Profiles of 24 Native language programs are arranged alphabetically by language and include program base, goals, brief description, instructional materials used, funding and other support, and contact information. A table summarizes the programs' services, settings, and target groups. The languages covered are Cherokee, Muscogee (Creek), Choctaw, Kiowa, Cheyenne, Comanche, Dine (Navajo), Keres, Osage, Seminole, Shawnee, and Tewa. Programs are presented in schools, colleges, preschools, and community settings. Appendices include regional task force members, advice about Native language education drawn from questionnaire responses, 9 recommended readings, text of the Native American Languages Act, the Navajo Nation's long-range language goals, 7 Web sites and listservs on Native languages, and 30 relevant organizations. An index is included. (SV)
