I use wishlists on both B&N.com and Amazon, but I always seem to forget to update them! I started the Word document (now on Google docs) when I wanted to keep track of releases that hadn't been listed on Amazon yet (like Jim's Red Hood's Revenge, which actually might not yet have a pubdate, or Magic Bleeds by Ilona Andrews, which is scheduled for June 2010). It's also convenient for me to print off and take with me to the store. :)
