Are international editions of college textbooks any different from U.S. ones?

The differences are usually minor. Things like page numbers, or specific examples cited, or review questions being slightly different, but the text will be the same. International editions are a great way to find cheaper textbooks and are among the various results I find when using a href="http://www.bigwords.com" rel="nofollow"http://www.bigwords.com/a to find cheapest textbooks. They are a textbook search engine that searches all the online textbook retailers and rental sites to find you the best prices. And at the end of the semester you can use them to search for resellers to sell your book to. All the search results are organized by price so you can buy your books for the lowest prices and sell them back for the highest.
