This collection contains digital atlases, farm directories, and plat books for all 99 Iowa counties. We have collated these from a variety of online sources, and provide them here as a single source for all online Iowa Atlases, Iowa Farm Directories, and Iowa Plat Books.
Many research problems can be solved with the use of maps, atlases and gazetteers. Maps that show the location and approximate size of the town also revealed neighboring communities and nearby landmarks, such as rivers and mountains, which may be noted in an ancestor’s diary or photo album.
Research Strategies
Researching with Iowa Atlases
An atlas is a collection of maps and can be useful in more ways than one. In addition to pinpointing the location of the family homestead, commercial atlases include advertisements of local establishments and biographical sketches of its subscribers, in some cases accompanied by live lithographs or photographs as well.
Researching with Iowa Farm Directories
As with the city directory, county or rural directories can be helpful in placing an ancestor in a certain place at a certain time. These directories, sometimes called farm directories, cover a much larger area (an entire county or, in the regional directories, several counties) and were used to advertise goods and services in rural areas.
Researching with Iowa Plat Books or Land Ownership Maps
According to Wikipedia, a plat “consists of a map, drawn to scale, showing the divisions of a piece of land.” Genealogists find plat maps exceedingly useful in that they usually show who owned a particular plot of land during a given year. Plat maps can assist in locating nearby cemeteries, figuring out who were their neighbors (as they might be relatives) and determining how long a person owned the land.
