This week is the American Library Association's Banned Book Week, an awareness campaign dedicated to opposing censorship. To mark the occasion, Time magazine has put together a list of some of the 10 most challenged books in history. It's sobering to see how many great books are on that list - indeed, my favorite novel, Lolita by Vladimir Nobokov, is on the list. Imagine the sheer cultural loss if censorial organizations still had the power to suppress books.
