This electronic bibliography brings together the nine books that comprise the Bibliography of the Geology of Missouri, published by the Missouri Geological Survey and its predecessor agencies from 1945 through 1972. As such, it includes all bibliographic citations that appear in Volume Second Series numbers 31, 38 and 42 and in Information Circular numbers 18, 19, 21, 23, 24 and 25. The version presented here contains some citations for literature published after 1972, and subsequent versions will contain more as the bibliography is gradually updated. Search options for specific geologic subjects are provided. We welcome and encourage comments from users.
