These files were prepared by the Federal Writers' Project predominantly for the Iowa guidebook, Iowa, A Guide to the Hawkeye State, in the American Guide Series. Their arrangement is roughly correspondent to their use in the book. The first series is arranged according to the subject numbers found on the original files. Some files had been given titles, others had not, and were assigned titles by the processor in the nineteen seventies. These new titles are in parentheses. This series seems to have been most important in the preparation of the first section of the Guidebook, "Iowa Past and Present." At the end of this series is a box of miscellaneous "Histories, Guides, and Articles," also prepared by the Project.
