For fans of J.D. Salinger, the legendarily reclusive writer who hasn't published anything for the last 40 years (but who is rumoured to have a pile of manuscripts in a safe), here's a treat: 21 uncollected stories, which have only been published in magazines. All from the '40s, and a number of them feature Holden Caulfield, the equally legendary protagonist from 'The Catcher in the Rye'.

Update: Hm, this link looks long-dead. As an alternative, the New Yorker offers 13 of Salinger's published stories online (subscription required).
