Great Reads for Organizers!

Great how-to classics on organizing - books that all organizers might find useful - and recent releases having to do more explicitly with online organizing. Got a book to recommend? Let us know. (We'll credit you if we post it.) And please vote and comment about books you've read to help fellow organizers find their way to good reads. This is also the place to vote up any books for which you'd especially like an Author Talk!
