does steve weiss have an online site?

No, he doesn't. As long as what you're looking for isn't too obscure, you may want to check out www.jwpepper.com and www.sheetmusicplus.com. They both seem to have adequate selections. I think these are the correct addresses. www.studio4music.com is another good one. A lot of what I have played has been published by them (it's a division of Alfred Publishing Company. Hope this helps!
