For an uber-cool and ultra-minimal look, the Umbra Conceal Bookshelf [$13] mounts to the wall and becomes invisible behind a stack of books, giving the books the appearance of floating in mid-air. Attach the sturdy, L-shaped shelf to the wall with the included mounting hardware and slide one book onto the ledge so that the ledge is sandwiched between the book’s cover and pages. The patented design by Miron Lior is the winner of many design awards including the Umbra Pratt Design Competition.
