When a magazine is placed in a bookcase the outer pages are liable to turn back if it is inserted with the back on the outside. To overcome this difficulty I made clips for each magazine to hold the open pages together. Each clip was made of wire, about 8 in. long, shaped as shown. The width of the clip is made equal to the thickness of the magazine and the extending ends are slightly pressed together so that they will spring and grip the pages. - Contributed by W. A. Saul, E.
