County atlases from the 1870s to the 1930s are available for all Iowa counties on microfilm.  Most were filmed using copies from the collections at the State Historical Society offices in Iowa City (SHSI) and Des Moines (DM). The microfilmed county atlases may be obtained in the Map Collection, then taken to the Media Services Department for viewing and copying.

In addition, the UI Map Collection staff have begun to digitize maps from selected county atlases (see http://digital.lib.uiowa.edu/cdm4/browse.php?CISOROOT=/maps )   This ongoing digitization effort is part of the Iowa Heritage Digital Collections (IHDC) project.

The Map Collection also contains a microfiche set from the Library of Congress’ Geography and Maps Division, titled "19th Century Land Ownership Maps of Iowa." Fiche may be viewed in the Map Collection and taken to Media Services for copying.

Counties and years represented in that microfiche set are as follows:

In addition to older county atlases and land ownership records in film, fiche, and digital format, the UI Map Collection also owns newer plat books, from the 1950s and 1960s on, for all counties in Iowa.  Holdings for most plat books are in the online catalog.
