If you are still following this thread, you'll find Godfrey Library here: http://www.godfrey.org/
The AGBI link is near the center of the page. If you're lucky, perhaps one of your friends or someone you know from a list you subscribe to will have a membership to GL and can help you. Otherwise, it seems that you can order the info you seek without a membership, if I read the request form correctly.
Let me know how it goes - there are a few AGBI articles I'm interested in seeing, myself.
