Untitled (Paperbacks) is a room-sized installation that feels empty but isn't quite: on all four walls hang rows of long white objects that look like shelves but are not, for they are plaster, not wood, and their surfaces are uneven, and vacant. These regularly spaced tiers suggest a library without books, yet books were here, and their traces remain. Whiteread made these objects by casting shelves of paperbacks, whose slightly differing sizes account for the plaster's uneven surfaces. Look closely, too, and you may see a residue of paper embedded in the casts, the edges of the pages caught as the plaster dried.

Whiteread specializes in the sculptural reversal that makes a solid object speak less of its own material presence than of objects that are no longer present, yet maintain a ghostly presence in their absence. The early work of this British artist comprised castings of everyday furniture—mattress, table, bathtub—in mediums from resin to concrete. She next addressed architecture, as in Untitled (Room) (1993), a plaster work also in the Museum's collection: here empty space becomes an opaque cube marked on its outside by the lines of a room's windows and door. Her more recent outdoor Holocaust memorial in Vienna is another room, once lined with books, which left their marks on the outside of a sealed block, symbolizing the lives and the culture lost to Nazi persecution. Untitled (Paperbacks), by contrast, is a library you can enter. Although there is nothing to read in it, it is filled with the knowledge, ideas, and memories contained in books, even if you must bring those associations with you into this serene, but haunted, place.
