Acknowledgments
The authors would like to thank Laurence Worms and Ashley Baynton- Williams, who both read the text at an early stage and generously contributed their expertise throughout.
Thanks also go to those map-dealers who made their image archives freely available: Daniel Crouch Rare Books, Boston Rare Maps, and Barry Lawrence Ruderman Antique Maps; and to the many museums and libraries noted in the text. Finally, thanks are due to David Bayley, who did the extensive Internet search on dissected maps, and to Anne Williams, for her valuable help with American Geographical puzzles.
