Definition of term:: Slipcase

  • Slipcase
    An open-ended box, usually made of cardboard, but sometimes covered with cloth, into which a book is slid in order to protect it. These are sometimes supplied by the publisher with the book, most often in the case of expensive limited editions such as the limited edition of Ernest Hemingway's A Farewell to Arms, for which each slipcase was numbered on an applied printed to label to match the book. Sometimes slipcases are ordered by collectors to be custom made for a specific book. If a book was published with a slipcase, and it is missing, it has a negative effect on the value of that copy.
