On June 10th, 1815 Thomas Jefferson made a remark that would surprise no one, "I cannot live without books." During his long life, Jefferson collected thousands of books, and even though his collection was pared down due to a fire in his home in 1770, he quickly regrouped and began adding to his collection. In 1815, Congress purchased his library for $23,950. This digital collection from the Library of Congress pays homage to this tremendous collection by offering visitors several interactive features about Jefferson's books, an object list, and an event calendar of related lectures and talks on the collection. Visitors may wish to begin by exploring the "Themes" area, which divides some of Jefferson's books into categories like "Memory", "Reason", and "Imagination". Each section contains selected images from works like a 18th century Builder's Dictionary consulted by Jefferson and a collection of Machiavelli's political works published in 1768. For a more thorough examination, the "Interactives" area provides access to a number of full-text versions of some of these books.
