TJMind is a way to interactively explore and interpret Jefferson's life, letters, and influences, try it below!

Select a collection from the menus on the left to find out more.

Here at the TJMind portal site you can explore computer-generated topic models of Thomas Jefferson's readings and writings. If it's your first time visiting the site, you may want to watch the videos below to learn what you can do with topic models at this site.

This demo presents models of two sets of documents: (A) the documents in the Thomas Jefferson Letters, Randolph Edition (1829), which includes Jefferson's Memoir, and (B) a combined corpus of the Randolph edition with 166 books from Jefferson's retirement library.

The next phase of project development will bring online models of all 552 books he collected during his retirement (from his return to Monticello in 1809 until his death in 1826) along with the entire series of letters from this period. Subsequent phases will expand to include his earlier libraries and letters.

You may choose which set of documents to search, or simply begin by typing in the search box to locate books and letters from the combined corpus. Clicking will select a document at random. You should then click 'Visualize' and choose among coarse-grained (20-topic), medium-grained (40-, 60-), and fine-grained (80-topic) analyses. (40 is a good choice to start.) You will be guided further on the page that loads.

You may also begin by viewing a letter that Jefferson wrote in 1816 to his son-in-law about his grandson's education. This letter is a featured letter at Jefferson Library at

Please watch the videos to see the interface in action.
