ABSTRACT:
An adjustable and self-locking rack or support for firmly holding one or more books or the like in an upright position on a planar base member. The rack includes a pair of manually adjustable bookends having dovetails thereon which are slidably received in a longitudinally extending dovetail groove in the base member. The bookends are thus slidable or adjustable on the base member and, when moved into engagement with the books, are automatically self-locked to the base member due to the lateral pressure of the books to thereby firmly hold the books in an upright position on the base member.
