Senator Thomas F. Eagleton and Society trustee Henry J. Waters III established the Eagleton-Waters Book Award to recognize the author of the best book published on the political history of Missouri. The award is presented biennially, and winners receive a certificate and $1,000. The executive director selects a committee to review the nominations, which are received from publishers and authors. Books copyrighted in 2011 or 2012 are eligible for the 2013 award. The deadline for submission of nominations is July 1, 2013, and the winner is announced at the fall annual meeting.
