...Molly, who recommended The Book Thief as her new classic. Thank you to everyone for your entries. The answers to the question make a great to-be-read list. Molly, do get in touch, I have emailed you so you should have my email address, if not leave a comment and I will try again!
On a different note... I came a cross something on the Picador blog which might be of interest. It is the description of the modern paper trail left by publishing a book, and details the sorts of things that Picador archive. I thought other might be intrigued so if you haven't read it already you can do so here.
