April 2011 began the sesquicentennial of the Civil War. Launched in the midst of this heightened awareness of the Civil War, dozens of organizations pooled resources to create a major digitization and scholarship Web project that presents a comprehensive picture of the conflict along the Missouri-Kansas border.
The Kansas City Public Library, the lead institution in partnership with area archives, libraries, historical societies, and the Freedom’s Frontier National Heritage Area, received three large grants to catalog and digitize diverse collections of primary source documents from both sides of the state line, solicit original scholarly content, and design a website with cutting-edge features including maps, a Border War timeline, and a relationship viewer that allows users to see the historic interactions proven by the documents in the collection. The website, Civil War on the Western Border: The Missouri-Kansas Conflict, 1854-1865 , launched on August 21, 2013. Although the site is now fully implemented, new content and features will continue to be added to all areas.
The Missouri Valley Special Collections has a large amount of materials related to border warfare and the Civil War as a whole and the trans-Mississippi areas of conflict. Included are numerous published official records for the Union and the Confederate armies and navies, regimental histories, as well as individuals' manuscripts, diaries, and other resources. Many materials assist in genealogy research. See the following links for resources and check the online catalog  for specific titles.
