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 our archive and library, finding aids for researchers, scholarly publications, and public programs.

OER Programs...

Tucson Convento Late 1890sTucson Convento, late 1890s
  • complement Arizona State Museum’s research in pre-Columbian archaeology of the southwestern United States and northern Mexico;
  • explore the ethnohistory, documentary history, and political ecology of the region;
  • facilitate public programs and interpretive tours of Spanish colonial architectural treasures and other historical sites.

Documentary Relations of the Southwest (DRSW)

Documentary Relations of the Southwest (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 of them collected by the Jesuit Historical InstituteOpens in a new window, 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 place names, architecture, food, and many of the southwestern cultures have their origin in the history of this region. The 'Southwest' in this case covers Texas, New Mexico, Arizona, California, and northern Mexico—all of what was northern New Spain.
