Two other points on renewing: (1) Renewing takes literally seconds to do on the Step 2 page. It takes longer for me to write this point than accomplishing a renewal that hasn't yet expired. (2) If one fails to renew in time, and no one else grabs the book, going through step 1 gets you the book again. You have to go through the motions of downloading the book again, but you don't have to keep that new download as presumably what you are working on is more polished.
