Charles King published over 60 books and novels relating to military life, western adventure, and frontier and pioneer life. While he had published quite a bit before 1893, he lost much of his royalties when the bank he used failed. He then lost most of his books and papers in a warehouse fire. This pushed him to come out of his retirement back into the military, hence his involvement with the Volunteers from Wisconsin. He also began writing and publishing again in his non-military free-time.
In 1963, C. E. Dornbusch published a bibliography of Charles King’s books from the National Library of Australia. Many of the books in the McFarlin Library Special Collections can be found in the bibliography and have written markings to indicate if they are listed in the bibliography or if they are undocumented by Dornbusch. All of these books, including the C. E. Dornbusch bibliography can be found by searching the Charles King Library.
