Based in the History Department at the University of Tennessee, Knoxville, the James K. Polk Project sought to locate all extant letters by or to the United States’ eleventh president (1845–49) and to publish an annotated edition of selected letters in print and online. Students, scholars, and anyone interested in U.S. history can use these resources to learn about one of the most consequential presidents and about a key period in the country’s development. Since beginning its work in 1958, the Polk project has published fourteen volumes of the Correspondence of James K. Polk. All are held by numerous libraries and hardcover editions are available for purchase through the University of Tennessee Press. They also are available online as open access titles. In 2019 the project completed work on the fourteenth and final volume, which covers the last year of Polk’s presidency and his brief retirement.
