This material was probably kept on a shelf in the governor's office for speedy reference. The series contains works, usually published, regarding Kansas subjects or subjects that may have an influence over the lives of Kansans.

These pamphlets and books comprising the reference material series were pulled from the General Files Series immediately preceding because of their bulkiness, unrelatedness, or general need for separate listing. No previous clear order existed to these materials.

The materials have been arranged by subject or area of treatment (for example: agriculture) and are sublisted in each subject by issuing authority (for example: Department of Agriculture, Kansas Wheat Commission, etc.). The title of the work is listed next to the issuing authority.
