Is there much difference when college text books come out with new editions?

I'm taking a political science class and the book that is required is $120 dollars at the school bookstore I found a girl who is selling the same book for 20 dollars. The book store's book is the 10th edition and the used book that I want to buy is 8th edition would their be much of a difference in the material text?Is there much difference when college text books come out with new editions?
Usually the changes are in the homework questions at the end of each chapter. There's a pretty big difference between 8th and 10th, though -- I wouldn't risk it, it has updates from the 2006 elections. Look for it on Amazon or TextbooksRus or other similar websites -- even eBay -- you'll be able to find it cheaper than in the school bookstore. I saw one new listing for around $70, including shipping.
It can be extremely varied, especially in a course like political science. I know it's painful, but it's probably better to by the book from the bookstore. If she's selling it that cheap, it's probably outdated anyway.Is there much difference when college text books come out with new editions?
you should ask your professor if its okay. chapters might be different but most of the information should be about the same.
The new version appears to have a review of the 2006 election. the older version was published in 2004. Probably this will make a difference.



Try Amazon.com. They have a lot of books, used and new, in the $70 range.
