I was actually able to get the ISBN numbers online - woooo! But, what I'm wondering is - will there be any problems with certain books that require online access. I know me, I barely use the books to begin with - I hardly know why I buy them...

And, often times older editions have the same material inside, just arranged slightly differently. Any opinions on that? Because if I get one that's a year older - Let's say - more than significant savings...
