In the second half of 1845 the focus of Polk's correspondence shifted from those issues relating, to the formation of his administration and distribution of party patronage to those that would give shape and consequence to his presidency: the admission of Texas, preparation for its defense, restoration of diplomatic relations with Mexico, and termination of joint occupancy of the Oregon Country. In addition to the texts, briefs, and annotations, the editors have calendared all of the documents for the last six months of 1845. Entries for unpublished letters include the documents' dates, addressees, classifications, repositories, and precis. The Polk Project is sponsored by the University of Tennessee and assisted by grants from the National Historical Publications and Records Commission, the National Endowment for the Humanities, and the Tennessee Historical Commission.
