J.D. Salinger was one of the literary world's great writers of the 20th century, a man who achieved regular acclaim, yet rarely stepped out of the shadows long enough to accept the praise that was so regularly passed his way. The famous recluse became particularly closed off from society as he grew older, and as his age advanced his published works became less regular. However, the biographers of the acclaimed writer believe his writing may not have stopped as he grew older, as they reckon the author had more work in his archives than he was letting on.

David Shields and Shane Salerno, the authors of the biography Salinger, have revealed that the author has working on a plethora of new titles in the years leading up to his death, and they have since told the Associated Press that Salinger might have a few complete works that are ready for a post-humous release. Salerno and Shields claim to have acquired a collection of Salinger's unpublished works, including further tales from his Glass Family saga about recurring protagonists Franny and Zooey. Their biography contains a detailed catalogue of the unreleased works, works that have since been verified by Salinger experts as being works by the late author.

One of the most exciting prospects to emerge from this newly unearthed treasure-trove of unpublished works includes a follow-up story to his most famous work, Catcher in the Rye, which will follow protagonist Holden Caulfield following the events of the first book as he joins the Allied Forces during the Second World War before experiencing a spiritual re-awakening. The biography Salinger is expected to hit bookstores and online platforms on September 3, with a follow-up documentary from Salerno due to air on PBS on September 6. The two biographers claim that the unpublished works will be ready to published sometime between 2015 and 2020.
