If you are looking for a specific letter at the Jefferson Library, there are several sources to choose from, explained below.
Jefferson's Published Papers
There have been three major publications of Jefferson's correspondence:
- Paul Leicester Ford edition, (Putnam, 1892): 10 volumes
- Lipscomb & Bergh edition (Thomas Jefferson Memorial Assoc., 1903-1905): 20 volumes
- Boyd edition (Princeton, 1950- ): 31 volumes to date
The first two editions encompass Jefferson's entire lifespan, but are not as comprehensive as the Boyd edition; however, the Boyd edition is still in progress, and only covers the years 1760-1800.
Many of Jefferson's writings have also been made available online.
- Thomas Jefferson Papers, from the Library of Congress's American Memory Project
- Definitive Edition of the Lipscomb & Bergh compilation
- Massachusetts Historical Society's Thomas Jefferson Papers: An Electronic Archive
