I'm one of the co-editors of the second edition of Field Guide, and I'd like to point out that most of the customer reviews posted here refer to the first edition. We've changed just about everything in this version, including the font size. Most importantly, we have a huge list of world-class contributors -- Tim Ferris, Phil Yam, Tom Siegfried, Lew Cope, Nancy Shute, David Everett, Carey Goldberg, Ron Seely, Lee Hotz, Janice Tanne, Colin Norman, Joe Palca, Kathryn Brown, Carl Zimmer, Alan Boyle, Tammy Powledge, Mariette DiChristina, Gareth Cook, Antonio Regalado, Rob Kunzig, George Johnson, Jamie Shreeve, Rob Kanigel, Shannon Brownlee, Marilyn Chase, Sally Squires, Paul Raeburn, Kevin Begos, Steve Hall, Ken Chang, Michael Lemonick, Andy Revkin, McCay Jenkins, Glennda Chui, Usha Lee McFarling, Cris Russell, John Toon, Earle Holland, Joann Rodgers, Colleen Henrichsen, Frank Blanchard, Mary Miller, Marion Glick, and James Gleick. We tried to get Amazon to update their information on this page, but no luck -- so you'll have to just browse in some other way. Believe me, it's a beautiful and useful book.
