The series is a listing of the subject headings under which are filed materials collected as a part of the State Wide Historical Project, the effort to publish the Wyoming Guide, and the other smaller projects of the Wyoming Writers' Project. Those folders bearing numbers 1151 through 1599 comprise the bulk of the material collected for the Wyoming guide book. The remaining folders contain the data collected for the other projects, like the history of grazing, history of the Wyoming National Guard, and Wyoming’s submission for “America Eats”. For digital images see Wyoming State Archives website.
