From The Telegraph:
Was JD Salinger best known, in later years, for being the most celebrated literary recluse in the world? After 1965, he withdrew from engagement with the literary world, emerging only at the hands of the occasional journalistic tale of stalking, in a furious-looking snatched photograph, or some unsubstantiated rumours. He made no distinction between a respectful inquiring scholar like Ian Hamilton and any number of scandalous muckrakers.
That wasn’t his real fame, however. The four books he published before that withdrawal have gone on selling in steady, substantial numbers. Catcher in the Rye in particular has never stopped being loved by a huge audience since it was taken up by the first generation of campus near-dropouts. The two stories in Raise High The Roof-Beam, Carpenters are the celebrated New Yorker oblique tender style at its pinnacle and summit. Some people thought that with Franny and Zooey, Salinger demonstrated a love for his fictional family, the Glasses, which no reader could be expected to match. For others, it stopped, exquisitely, on the verge of the sentimental.
