Book Magazine has published a list of classic bestsellers. One can quibble with their criteria (I'd hardly classify Clan of the Cave Bear as a "classic"), but the list makes for interesting reading nonetheless. It's amazing that books like The Catcher in the Rye and To Kill a Mockingbird continue to sell around 500,000 copies a year (someone's heirs are raking it in). My old favorites Atlas Shrugged and The Fountainhead come in at #19 and #35 (in 2002 they sold 130,000 and 81,000 copies respectively). No wonder the Ayn Rand Industry keeps growing.
