1From Thomas Jefferson to Oliver Parsons, 14 February 1823 (Jefferson Papers)
I have duly recieved your favor of Jan. 29. in which you are pleased to request a copy of my works to be deposited in your library. I have never published any work but the Notes on Virginia, of which I have but a single copy, and they are now very rarely to be found. all other writings of mine have been of an official character, and are only to be found among the public documents of the times...
