The Shape of the Wire Makes It Easily Applicable to Any Open Bookshelf

Ill: The Shape of the Wire Makes It Easily Applicable to Any Open Bookshelf

A brass wire, 26 in. long and about 1/8in. in diameter, is bent, with the use of a vise or pliers, to the shape and dimensions shown at A. When the wire is placed on the bookshelf, as shown at B, it prevents the end book from falling. Its location can be changed as books are added to the shelf. - Contributed by John Y.
