<p>Do we always need to purchase the newest editions or can we simply save some money and buy an edition that is only a year or two old? Can there really be that many changes to the book?</p>
<p>depends on class and professor.</p>
<p>i hope they allow this, cause my brother has lots and lots of new looking books from 8 yrs ago.</p>
<p>8 years is a long time</p>
<p>totally depends on the class.</p>
<p>some classes require you to do problems out of the book, so book edition matters a great deal. for some classes, I didn't even buy the book cause I din't really need it.</p>
<p>8 years is pretty long. you'll most likely need to buy at least one new textbook lol</p>
<p>Compare the old edition to the new. If the pages match up and the problems are the same (if it's a book w/ problems, that is) then it might be okay. If it doesnt work out, you can try to return it and buy the new one. I've bought old editions before, and if I needed material from the new one, I would borrow it from a friend.</p>
<p>You can probably use the old books, but it makes life incredibly difficult. If you need to borrow the book from a friend, your friend probably needs it at the same time. And you would have to plan your schedule on when you can get access to the book. If you're paying so much for college already, make it easier for you to do well in classes by buying the right books. That is, unless you're really really tight on cash.</p>
<p>it's a good idea to always check on <a href="http://www.half.com%5B/url%5D">www.half.com</a> or <a href="http://www.amazon.com%5B/url%5D">www.amazon.com</a> and compare their prices from the cornell store's prices. Usually, you can save quite a bit if the book can be found used. Even if it's a new edition, you'll still find books for $30 to $40 cheaper from those sites.</p>
<p>probably not if it's a class with problem sets like physics or chemistry because they will make you do hw from the book and if its a different edition then the problems will be different</p>
