This large image (4400×2364 pixels) is completely marvellous: a genuine history, reaching back into trends from the dawn of literature, and with a healthy chunk of 19th century gothic/mystery in there. Makes me very happy, especially in terms of fond memories of books I've enjoyed.

Thomas Jefferson's entire library - and his reviews of books in it - exists as an account on LibraryThing. I'm glad that things like this exist in the world, and that the Internet makes them possible.
