History's Coming To writes "xkcd creator Randall Munroe has revealed on his blag that the acclaimed stick-figure comic will be produced in real dead-tree book form. Fantastic news for all fans of comedy, maths, science, and relationship screw-ups — especially given that the book will be sold in aid of the charity 'Room To Read.' Rumors that the book contains a joke in the ISBN remain unconfirmed." The NY Times article that Munroe links (registration may be required) is from April of this year, and I am amazed that this community didn't note the story at that time. The book will be published by breadpig, which was created by Alexis Ohanian, one of the founders of reddit.
