University of Arizona


We have one of the nation's finest collections of archival materials as well as printed texts on the Borderlands of the Southwest and Northwest of Mexico, from Baja California to Tamaulipas, Mexico.

These collections document the region's culture and history, from colonial period to present, including accounts of Native Americans and their ancestors, the impact of Spanish and Mexican settlement, and the influx of Americans and others into the region during the 19th century.
