    The Archives maintains a small reference library containing published books relating to Jefferson County history as well as Colorado history. These reference books are available for use in the Archives’ Reading Room only; no material from the Archives may be checked out. (Some of these materials may be available at local libraries.)

    We also have Jefferson County Historical Commission publications available for sale, including current and back issues of Historically Jeffco magazine and From Scratch: A History of Jefferson County, Colorado.
