Office of Ethnohistorical Research
Arizona State Museum's Office of Ethnohistorical Research (OER) conducts, facilitates, and interprets research on the peoples of the southwestern United States and northern Mexico, providing access to a substantial collection of Spanish and Mexican documents through an archive and library, finding aids for researchers, scholarly publications, and public programs. OER holds approximately 8,000 secondary works, reference materials, indexes to major archival collections, maps, ephemera, and guides to paleography and translation and connects with ASM's Library collection of 50,000+ volumes related to southwestern archaeology and history.
Please email us at ASM-OER@email.arizona.edu with any questions about OER resources.
OER Publications and Research Projects
The office is publishing two series of documentary histories that spotlight the northern frontier of New Spain. The first covers the evolution of the presidial and militia system, with four volumes published to date (2012) and a final edition in progress. The second series focuses more directly upon Native American peoples of the region, with three volumes published and two more in progress. These projects have received support from the National Historical Publications and Records Commission (NHPRC), the National Endowment for the Humanities (NEH), and the Southwestern Foundation for Education and Historical Preservation.
- Research on land grants and water rights in the greater Southwest has resulted in technical reports and expert witness testimony, with scholarly manuscripts in preparation.
- OER has researched regional environmental change and political ecology with support from the Forest Service, Bureau of Land Management, CLIMAS, and agencies that focus on the upper San Pedro watershed.
Documentary Relations of the Southwest (DRSW)
DRSW provides the research tools and finding aids to the written record that began with the arrival of the Spanish explorers in the 1530s. The 1,200+ microfilm reels of documents, many collected by the Jesuit Historical Institute, include the diaries of explorers and reports of missionaries and soldiers. They date from the first written accounts of contact with indigenous peoples in the 16th century to the Mexican declaration of independence from Spain in 1821. The "Southwest" in this case covers Texas, New Mexico, Arizona, California, and northern Mexico—all of what was northern New Spain.
