Every once in a while I like to spotlight new self-published books that may be promising, especially if the topics are unusual.
William Pollard's Forts and Posts in Kansas During the Civil War: 1861-1865 "provides details on all the military posts and forts in Kansas from 1861 to 1865. Some posts were U.S. Army posts, others were forts established by community militias and one was even a permanent Confederate guerrilla camp. Numerous maps show where all these posts were located and one appendix provides geographic coordinates of all of them." I'm not familiar with Pollard but his 1991 book on the Lawrence Raid (Dark Friday) is still frequently referenced in new works of good quality and the Kansas State Historical Society thought enough of his work to provide him with a research grant to further his study of Kansas forts. I will definitely pick up a copy at some point.
