<p>I need help with buying textbooks for Chem 142.
I went on Uloop.com to check it out and personally I would like to
order them online and get it shipped. But anyways </p>
<p>on sites like amazon.com and half.com, the chem 142 books are
published in 2007, while the books that students were selling on Uloop.com
are published in 2009, is there a big difference that I just HAVE to buy
the 2009 one? or can I just buy the 2007 published book.</p>
<p>And if anyone knows any other good sites for buying textbooks, please share ! (:</p>

<p>I’m buying the most recent editions mainly because my books are all for calc and physics, so I want to make sure all of the assigned problems match up, and because I know the series of physics books underwent a significant overhaul between editions. Contact your professors or former students to see if prior editions are compatible.</p>
