That is a good idea, and it works if they have the identical book, but some of the editions I have used different wording, or when searching on the ISBN it won't turn up. I do cut and paste when I can. (Sometimes you can piggy back from other eBayers if they've already copied it, but pay head to the proofreading thread and be sure you're not repeating their mistakes or it is conspicuous where you stole found your copy). :)
