The novel was published in trade paperback format by Penguin Young Readers Group, a division of Penguin Random House, on June 14, 2011.[6] Thirteen Reasons Why had remained in hardcover long past the usual one-year release-to-paperback schedule due to its continued grassroots popularity and sales fueled by author participation.[7]
On December 27, 2016, the Tenth Anniversary Edition of Thirteen Reasons Why was published in hardcover, also by Penguin Young Readers Group.[8] This edition includes new content including, but not limited to, the author's original unpublished ending for the book, a new introduction, an essay from the author, and pages from the notebook that the author used while writing this novel.[9]
