I misspelled Duilio Carpitella's first name in the preface, but at least seemed to have gotten it right in the rest of the book. Sorry, Duilio.
(This is corrected in the paperback edition.)
It was exasperating, but also exciting, to discover that this area would not stand still just because I had sent the final version of the manuscript to the publisher. Robert Reid and Anton Hanegraaf found improvements for several dissections in the book, and Gavin Theobald improved several three-dimensional dissections. And I continued to identify that additional piece of information that makes this area so interesting.
I would like to thank Gavin Theobald, Anton Hanegraaf, and Robert Reid for permission to reproduce these new dissections. I would like to thank Teresa Uteseny and Bernard Lemaire for help in explaining the significance of the Chenez political cartoon discussed in the Afterword section of these updates. I would also like to thank Le Monde for permission to reproduce the cartoon. A thank you to David Eppstein for pointing out that Fig. 8.19 applies to a class of solutions to three squares to one. I would like to thank Volker Priebe and Edgar Ramos for permission to reproduce their work on dissection proofs.
I would like to thank Vladimir Belov for sending me copies of the sections of a number of Russian puzzle books that dealt with geometric dissections. I would like to thank Leonid Mochalov for sending me the 1996 edition of his book, plus additional material.
