Which mad man do you read like? The Battery Park City Library has been Tweeting links to books that have been making cameos on Mad Men, from Frank O'Hara's Meditations in an Emergency to Atlas Shrugged to F. Scott Fitzgerald's Babylon Revisited—and now they've added a photo gallery.

Some of the books spotted in Don Draper's office have included, The Hidden Persuaders by Vance Packard, The Lonely Crowd by David Riesman, The Image: A Guide to Pseudo-Events in America by David Boorstin, and The Hucksters by Frederick Wakeman. And of course, there was the scandalous book Lady Chatterley's Lover, which appeared in season 3 when "Joan returns a tattered copy to Marge, one of the switchboard ladies. The book, a 1928 novel that was banned for its explicit sex scenes and four-letter words, sparks Peggy's interest. With some prodding, she borrows it."
