An unpublished manuscript, entitled The Richmond Group of the
Cincinnati Province, compiled by the late William H. Shideler,
has been made available by the Division of Geological Survey as
Open-File Report 95-1. Dr. Shideler was a professor of geology

Shideler's typewritten manuscript was edited by Joe H. Marak,

University. Marak notes that the manuscript is outdated,
