When poet Eloise Klein Healy‘s new book A Wild Surmise: New & Selected Poems & Recordings comes out in 2013, it will come with bonus audio files of her reading her work. But instead of these recordings coming with a CD or DVD, readers can access them with a QR code.

Readers can use a QR code reader app to access 35 audio files of more than a hundred poems in the collection. (Readers who don’t have smartphones can access the content on the author’s website).

Healy’s publisher Red Hen Press is not the first to experiment with adding QR codes to books. Simon & Schuster announced this past summer that they would begin adding QR codes to all books beginning this fall. The Simon & Schuster QR codes link to author pages which include things like videos of authors and details about other books.
