As long as I can remember, I have been a big fan of Dover paperbacks. I was reminded of this as I started reading Howard Carter and A. C. Mace’s The Discovery of the Tomb of Tutankhamen (1923). There, at the bottom of the back cover, stood this bold claim:
A DOVER EDITION DESIGNED FOR YEARS OF USE:
We have made every effort 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, and will not drop out, as often happens with paperbacks held together with glue. Books open flat for easy reference. The binding will not crack or split. This is a permanent book.
Alas, this claim does not appear on more recent Dover paperbacks. In my collection, I have at least several hundred Dover books on chess, Shakespeare, ghost stories (a Dover specialty), mysteries, G. K. Chesterton, Anthony Trollope, John Lloyd Stephens, and numerous classics in the public domain. Not only were Dover books well made, they used to be relatively inexpensive. No more. I still follow them at their website and still occasionally order from them.
