<p>So on the book store site (where it tells you the books you need) it tells you a number (08, 09) that i assume to be the publishing date. Well, I found the ISBN and everything, and those numbers are always off by one.. What's with that?</p>
<p>If you’re using that script that goes with Greasemonkey, I think the ISBNs are for the workbooks or something, and the actual textbook is close to that number. I’m not quite sure why that happens… (I suck at computer scripts/programs.)</p>
