Marquand Library, normally located in McCormick Hall next to the PU Art Museum, is one of nine separate Princeton "branch" libraries, and is a premier art history, architecture, and archaeology library used by the entire campus and visited by scholars from all over the world. One will find books and exhibition catalogs in Marquand that are not available widely. Marquand also has a sizeable and growing rare book collection. More information about Marquand is available on its website.
NOTE: as of March 2021, Marquand is temporarily located in two reading rooms in Firestone Library (C Floor) while a new Art Museum is being constructed. The physical collections are all off-site and requests but me made via the library catalog.
Marquand is fully non-circulating. Any item in use by someone else (i.e. on a shelf or in a faculty office) will have status ASK STAFF. Ask at front desk and we will do our best to retrieve the item in question for your consultation. (In some cases, "ask staff" books are not yet physically at Princeton, i.e. "on order.")
