There isn't a Manual of Caver Information, but the following list will give you a good basic grounding in Missouri Geology, Biology, Natural History, and Basic Caving Techniques. More specific information on certain topics can be obtained from issues of Missouri Speleology, by contacting the NSS, and Missouri Caving Grottos, and the publications divisions of the Missouri Dept. of Conservation and Dept. of Natural Resources, Geological Survey and Resource Assessment Division, both of which have many books and pamphlets for sale.
Most of these books are available through public libraries, or through interlibrary loan. A few may be obtained only through cave specialty bookstores, such as the NSS bookstore. A few are hard to get, but they are invaluable for what they provide.
