I have a hardback copy (although I do not wish to sell it.) I bought it 10 or more years ago, possibly at the park service office at Fort Davidson, although I'm not sure. It was published in 1986 by The Center for Regional History and Cultural Heritage at Southeast Missouri State University. Inquiries were invited to be mailed to:

The Center for Regional History and Cultural Heritage
Southeast Missouri State University
530 N. Pacific
Cape Girardeau, MO 63701

Maybe they still have a few copies floating about or since the original publishing date have developed a print-on-demand capability.
