For some time I have had two "home pages" -- my SFWA page, which contained my biography and bibliography, and my "Books for Sale" page at Mandala.net.
I have finally taken steps to combine the two into a single new, expanded Official Home Page, and I have moved it to a domain of mine own at
http://www.georgerrmartin.com/
The two old pages are gone now, so I would appreciate it if you would update your links ASAP.
And check out the new official page. It looks pretty good, and has some new features that I think will be of interest. We're adding more every day as well. I hope to able to update the page frequently.
