The story. We wrote a book because we thought the available texts weren't good enough. We talked to about 10 textbook authors before we started writing. They all advised against it: more work than you would think, slight or negative academic rewards, and little chance of financial gain. Now we know. But it hasn't been all bad. We started in 1992 and have re-organized the book 4 or 5 times since. We have enjoyed 13 international trips to work together in Ithaca, the Baltic Sea, and Bangalore. We intended to wite just a dynamics text, but then we added statics because many of the student dynamics difficulties had their roots there.The book was contracted by Saunders Publishing but then sold, with the whole Saunders College Division, to Oxford University Press where our friendly editor, presumably waiting for us to say ``ready'', is Danielle Christianson. Various pre-release versions of this book have been used at Cornell about 12 times and also at a few other schools. The book has had about 20 external reviews. Some people have read the book through and found it educational, despite the defects which have annoyed some others. We hope more and more people find the book useful as we continue to improve it.
