The Iowa Women’s Archives (IWA) has many collections of primary source material. We suggest that you start by looking at the Topical lists of collections: http://collguides.lib.uiowa.edu/search.php
Here are some examples of topics and collections that can be researched in the IWA. Most of the links take you to guides to the collections, called "finding aids." Some of the links take you to collections of documents that are available online, such as the Women's Suffrage Digital Collection.
