The second largest research collection in the state is located at the Iowa City branch of the State Historical Society’s research facilities. Holdings include local, state, and national histories; biographies; government documents, and current historical periodicals not all identical to the facility at Des Moines. Microfilm holdings are loaned between the collections. Of specific interest to genealogists are county histories, state census data, cemetery records, atlases, and plat books. Iowa newspapers, beginning in 1836, can be found in 10,000 bound volumes and 12,000 microfilm rolls (microfilm available through interlibrary loan). Fire insurance maps include more than 700 Iowa communities. Over 100,000 photographic images can be located by standard subject headings, geographical designations, or the portrait index.
