The life and works of J.D. Salinger have been much in the news after his recent death, and if you've been reading about him you probably know his last published work was "Hapworth16, 1924," which took up most of the June 19, 1965 issue of The New Yorker. The story takes the form of a long letter written to his parents by a seven-year old Seymour Glass (Franny and Zooey's older brother, who committed suicide in "A Perfect Day for Bananafish") from summer camp. It has never been published in any other form, and I once read that you couldn't even get a hold of it in back issues of The New Yorker collected at libraries, because Salinger fans had torn them all out.
Several years ago, however, I found a Hungarian web site that had published all of Salinger's work, not only including "Hapworth," but also his early, far less literary and accomplished stories. I checked in on the site the day he died, and it was still up. Today, I see that after all these years, it's finally been taken down.
Through the magic of Google caching, however, the web site lives on. So here now is "Hapworth 16,1924," the Glass-family story that almost no one has read. (You can also find it on the The New Yorker's online archive, but you have to have a subscription to the magazine. It's also available on the CD set of every issue the magazine released for sale a few years ago.)
Ironically for me, when I started to read the story (really a novella) a few years back, I just couldn't finish it. I thought it was by far the worst thing Salinger wrote in his post Catcher in the Rye days, an extremely unbelievable portrait of a child who is also a holy man/genius. Most critics felt the same way, and one theory of Salinger's subsequent hermitage and retirement from publishing is that it was in reality a giant fit over the story's reception.
If you're interested, better read it now, before someone discovers the Google loophole...
