As Colorado’s land-grant institution, Colorado State University holds a long tradition of sharing the results of agricultural, forestry, and other land-use research with farmers, ranchers, resource agencies, educators, and the general public. The Agricultural and Natural Resources Archive (ANRA) preserves and provides access to historical records that enhance understanding of the state’s agrarian and natural resource heritage. More than 100 collections contain source materials ranging from meeting minutes and correspondence to oral histories, diaries, maps, and photographs.

The ANRA offers in-person and online access to unique primary sources from Colorado Cooperative Extension, the Colorado State Forestry Association, National Park Service employees, the Rocky Mountain Farmers Union, and many other agricultural and resource organizations. New collections include materials related to Colorado diamond mining as well as to the regulation and marketing of products made from cannabis and hops in the state.
