Bagside: "A Dover edition designed for years of use!
We have spared no pains to make this the best book possible. Our paper is opaque, with minimal show-through; it will not discolor or become brittle with age. Pages are sewn in signatures, in the method traditionally used for the best books. Books open flat for easy reference. Pages will not drop out, as often happens with paperbacks held together with glue. The binding will not crack and split. This is a permanent book."
