More than 200 items related to reclusive author J.D. Salinger — and never before seen in public — will go on display at the New York Public Library’s main branch this month, The Post has learned.

Among the literary artifacts set to go on view will be the original typescript of the Manhattan-born author’s 1951 coming-of-age classic “Catcher in the Rye,’’ complete with Salinger’s own handwritten revisions.

“There are a great, great many readers out there who have their own rather profound relationships with him through his work and who have long wanted an opportunity to get to know him better,” Salinger’s son, Matt Salinger, said in a statement.

“While it is but a glimpse into my father’s life, it is my hope that lifting the veil a bit with this exhibition will throw some light on the man I knew and loved,” said the son, who helped organize the Manhattan exhibit along with his father’s widow, Colleen Salinger.

The exhibit — which will be displayed in the Sue and Edward Wachenheim III Gallery in the Stephen A. Schwarzman Building in Midtown — is scheduled to run Oct. 18 through Jan. 19.

Family photographs from J.D. Salinger’s childhood and youth will be part of the show, including one featuring him in a schoolboy cap straddling a boulder in Central Park.

Salinger superfans also will be able to view a bowl that the notoriously private novelist made at summer camp when he was about 10 years old — and kept until his death in 2010 at 91.

In addition, admirers will be able to glimpse Salinger’s notebooks, typewriter, wristwatch and personal letters to friends, fellow soldiers and authors and editors, including Ernest Hemingway and William Maxwell.

There also will be a bookcase full of books from Salinger’s personal library.

All of the items are on loan from the J.D. Salinger Literary Trust.

Born Jerome David Salinger on Jan. 1, 1919, to a Kosher cheesemonger father and a German, Irish and Scottish mother from Iowa, J.D. Salinger grew up on the Upper East Side and set many of his most acclaimed stories in the city.

Several of his short stories were published before he served in World War II, but he didn’t attain critical acclaim until “A Perfect Day for Bananafish” appeared in The New Yorker magazine in 1948.

After shooting to stardom with “Catcher,” Salinger tried to escape public exposure, even suing to stop a biography about himself by British writer Ian Hamilton in the 1980s.

The exhibit is set to coincide with the centennial of the author’s birth, said the library’s director of exhibitions, Declan Kiely.

“This exhibition presents Salinger in his own words,” Kiely said.

“[It] allows us to see Salinger from childhood to old age, revealing many facets of the writer: friend, father, grandparent, soldier, correspondent, spiritual seeker and, importantly, avid and eclectic reader.”
