I wouldn't use Yahoo-see-el-see, based on this experience, because I don't trust it. I'll start with my local catalog and go from there. Still, in the realm of hot new cool tools, kinda fun. Though if users believe this is a trustworthy resource, but it's not leading people to YOUR local catalog, beware, beware. "Yahoo says it's not there!" Go ahead and talk yourself blue in the face about how your catalog works... it won't matter.
