The Exhibition Room, or, why 'Ex' is the location designator for rare books in the Princeton University Library

When Pyne Library opened in 1897 [more], such rare books as the Morgan Virgils were shelved in a special room fitted with glass-fronted bookcases. The ground-floor room was the New World offspring of the Old World wunderkammer. Its purpose was public exhibition of private treasures. By extension, the Library’s location designator “Ex” (shorthand for “Exhibition Room” [more]) became the designator for the Library’s general rare book collection. It remains so down to today. A brief photo essay about the room follows.
