I want to put up a single, wall-mounted, oak or oak-effect shelf in my kitchen to house a few cookery books. Size up to about 700 mm long, and roughly 270 mm deep. The only problem is how to contain the books and stop them from falling over at each end. I just don't seem to be able to find anything whatsoever that will do the job! I would like it to look nice so don't want metal system type racking. Any suggestions appreicated? Thanks.
