We're celebrating the freedom to read this month, with the American Library Association's Banned Books Week launching on 22 September 2013.

Send us pictures of your favourite books which have been censored or banned – from Madame Bovary to Of Mice and Men and from Huckleberry Finn to Captain Underpants – and tell us why they've earned a place in your hearts and on your shelves.

Not sure if you own any? Take a look at Wikipedia's page on books banned by governments.

If possible, please show us your book in situ, e.g. on your bookshelf, or in your hands. And don't forget all pictures must be your own. We'll publish the best contributions in a gallery on the Guardian site.
