This case should have a back. Rabbets should be cut to receive the back, as in the case of the wall-shelf just shown (see Rabbet), the top and middle shelves being narrower than the lower shelf by the thickness of the back.
This case can simply be nailed together (see Nailing and Nail-set), but it will be better to groove the shelves into the sides (see Grooving).
See end of introduction to this chapter for directions about smoothing, putting together, and finishing. See also Scraper, Sandpaper, and Finishing, in [Part V].
Hanging Bookcase.—A simple and useful case for the wall (Fig. 286) can be made on much the same principle as the small case just shown. It is well not to make such cases very large, and, unless quite small, stock from ¾" to 7/8" in thickness will be suitable.
