I read a few Salinger books in a row back in my early twenties. Based on this obituary quote, I might like to read Franny and Zooey and Nine Stories again.
quoting Charles McGrath -
"Many critics admired even more “Nine Stories,” which came out in 1953 and helped shape later writers like Mr. Roth, John Updike and Harold Brodkey. The stories were remarkable for their sharp social observation, their pitch-perfect dialogue (Mr. Salinger, who used italics almost as a form of musical notation, was a master not of literary speech but of speech as people actually spoke it), and for the way they demolished whatever was left of the traditional architecture of the short story " the old structure of beginning, middle, end " in favor of an architecture of emotion, in which a story could turn on a tiny alteration of mood or irony. Mr. Updike said he admired “that open-ended Zen quality they have, the way they don’t snap shut.”
Mr. Salinger also perfected the great trick of literary irony " of validating what you mean by saying less than, or even the opposite of, what you intend. Orville Prescott wrote in The Times in 1963: “Rarely if ever in literary history has a handful of stories aroused so much discussion, controversy, praise, denunciation, mystification and interpretation.”
