What once seemed like an esoteric world now seems essential to our culture: the community of rare book dealers and collectors who, in their love of the delicacy and tactility of books, are helping to keep the printed word alive. D.W. Young’s elegant and entertaining documentary, executive produced by Parker Posey, is a lively tour of New York’s book world, past and present, from the Park Avenue Armory’s annual Antiquarian Book Fair, where original editions can fetch hundreds of thousands of dollars; to the Strand and Argosy book stores, still standing against all odds; to the beautifully crammed apartments of collectors and buyers. The film features a litany of special guests, including Fran Lebowitz, Susan Orlean, Gay Talese, and a community of dedicated book dealers who strongly believe in the wonder of the object and the everlasting importance of what’s inside.
