Doing That Library Thing

Another tool easy to become obsessed with - I only tagged a few books, because of course like most of us, my goal is to enter all the books in my personal library & I have to figure out exactly how I want to tag them - should I enter the bookshelf (or box as the sad case may be) where the book is located so I can easily find it, or am I kidding myself & should I just dive in and do everything? I'm so thankful for 2.0 - I really don't think I would have ever done this without the push - I've read about library thing, gone to the site - even played around, but taking the extra step & actually doing it myself, I probably wouldn't have done it. So thanks!
