From the Arizona Secretary of State:
As a Regional Federal Depository Library, the State of Arizona Research Library receives thousands of documents each year that record the activities of the Federal Government. Many of these documents involve the activities of federal government agencies in the state of Arizona.
Two new collections on the Arizona Memory Project, U.S. Census in Arizona- Federal Materials and Arizona Watersheds- Federal Materials, shed light on some of these activities.
The U.S. Census in Arizona – Federal Materials collection highlights census data that has been collected in Arizona since territorial times, including population, housing, and agricultural statistics.
The Arizona Watersheds-Federal Materials collection includes environmental reports and watershed assessments relating to Arizona water sources, their conservation and management. The census reports will provide genealogists and other researchers with important historical demographic data, and Arizona watershed materials will help scientists, historians, and policymakers find information that can help them understand Arizona’s historical use of the desert’s most important resource. These new curated collections of census and watershed reports are exciting to professionals and other interested people in these important fields.
