The Alfred J. Mokler Papers consist of holograph manuscripts, which is to say, manuscripts written in the author's hand, and typescripts from the Works Progress Administration's Federal Writer's Project which date to the 1930's. Much of this material may be found in Mokler's notebooks. In addition, researchers will find Mokler's unpublished typescript of a Chronology of Wyoming written for the Works Progress Administration. Material from some of these pages was used in Wyoming: A Guide to its History, Highways, and People. Mokler's papers also consist of approximately 300 original photographs, many of which were used in his publications. There are 15 scrapbooks of newspaper clippings, personal diaries and yearbooks, and 10 Letterboxes, of which contain publications and other materials Mokler collected as well as correspondence. Copies of Annals of Wyoming and books from Mokler's library were also gifted to the repository. Researchers will find a lot of Casper and Natrona County history in Mokler's papers.
