Since beginning its work in 1958, the project has published thirteen volumes of the Correspondence of James K. Polk. All are held by numerous libraries and are available for purchase. They also are available online for free. In 2019 the project completed work on volume 14, which covers the last year of Polk’s presidency and his brief retirement. It will be released in the fall of 2020. In the meantime, you can read most of the letters for that volume, without annotation, online.
