About the Collection

The Region 8 collection focuses on environmental issues and conditions unique to the American West, including Colorado, Montana, North Dakota, South Dakota, Utah, Wyoming and the 27 sovereign tribal nations. Special collections include: Green Buildings, Environmental Sustainability, Environmental Justice, and Western Wetlands. The library maintains paper copies of EPA reports, USGS reports, maps, environmental regulations and older journals.


The Region 8 Library was established in the early 1970s with a small collection of handbooks, reports and printed regulations. There have been several moves over the last 35+ years as the Regional office has grown and the library has expanded. Currently the collection includes over 20,000 EPA reports, books and journals.
