J.D. Salinger is dead.
He hasn't published anything since 1965, hasn't spoken to anyone since 1980. By all accounts, he was probably a hermit, a grump, and a cantankerous old man. In all likelihood, manuscripts or short stories he wasn't going to release will be found/leaked/released/something. Overall outlook: better-to-the-same.

...I am not going to cry in the library. Not, not, not.
