We have a database expert on the forums in the shape of our very own Paul M init?
I could knock up a entry only, sql, or dbase, and host it so members could add the information themselves as they find it.
That could be queried by anyone at any time, no need for a spreadsheet simply create the required fields and present them in pretty boxes.
But so could anyone else and I wouldn't want to deprive you of your project so I won't bother.
