“I am large, I contain multitudes,” Walt Whitman wrote in “Song of Myself.” And these days, New York includes an unusually large and varied amount of its most celebrated literary son.

The bicentennial of his birth on May 31 is being celebrated with events around town, including a marathon reading of “Song of Myself” in Brooklyn Bridge Park on Sunday. But even those who miss the festivities can immerse themselves in all things Whitman at three different exhibitions running deep into the summer.

“Walt Whitman: America’s Poet,” at the New York Public Library, surveys the landmarks of the poet’s public career, drawing in large part from its rich holdings. “Poet of the Body: New York’s Walt Whitman,” at the Grolier Club in Manhattan, takes a more intimate look. And Walt Whitman: Bard of Democracy,” which opens at the Morgan Library & Museum on June 7, features items from the Morgan alongside loans from the Library of Congress (including an errant 19th-century butterfly with a back story as colorful as its wings).

The exhibitions showcase manuscripts, books and photographs, but also some more unusual traces of the poet whose name, the exhibition at the New York Public Library puts it, stands as “a byword for the notions of inclusivity, equality, sensuality and the value of the individual.”
