J. D. Salinger did not want any of his early stories to be republished, thanks to the vagaries of the copyright laws at least three of his early stories had their rights available. These have been published in a small, illustrated edition.
The book is nominally 63 pages, but, with the exceptions of the illustrations, it has been printed on solely on the recto (right) side, the verso (left) side is blank except for the illustrations, so you have a book of around 30 pages, which you can read while accompanying someone to the doctor's office. You'll be done by the time you get there.
The Young Folks is set at a cocktail party, and is largely plotless, i.e., there are no incidents, and is best described as two people talking past each other.
Go See Eddie appears to have a back story, but it is implied, and ends on an implied threat of violence.
Once a Week Won't Kill You is the most evocative with hints of loss, old age, and senility.
It has been a long while since I read any of Salinger, though I still have his books, and I can't really offer any valid comparison of the early stories as compared with his later fiction, but the one that seems closest to the Salinger of Nine Stories is the last story with its description of tension between the man and his wife, and the sense of loss that envelops his aunt.
