Acknowledgments

We shall not list again the many correspondents and others who contributed notes or helped in other ways with the previous editions. We would, however, like to thank those who offered suggestions for this new edition with maps, general identification materials, and other tangible ways that helped to make this edition as complete as possible.

	The professionalism and support of Elaine Lillis and Elizabeth Gentile were invaluable. At Houghton Mifflin, Lisa White's editorial expertise, creative insight, and dedication to the project were indispensable. Anne Chalmers and Terry McAweeney provided editorial and technical support and guidance. Paul Jones photographed the plates, and Sandy Sherman copyedited the text. Larry Rosche created the electronic map files from Paul Lehman's data.
