As a table book-holder, this is probably the best and strongest form ever invented. As shown in the illustration ([Fig. 89]), the uprights slide and firmly grip a large or small number of books, according to the capacity of the holder. This contrivance has been adapted as a library book-carrier, by having strong hooks attached, which fit into staples affixed to the fronts or ends of bookcases. They are very useful for classifying and arranging books awaiting replacement or shelving.
There are other forms of book-holders and carriers with fixed upright ends, but they are not so satisfactory as the adjustable forms described.
