Now I know what you're all thinking, but don't. A flood of fans all logging on and saying "It's notable, we know it, it's historically significant and great and stuff" isn't going to help. Appologies for the characterisation, I exaggerate for comic effect.
What *will* help is references to published material that states that BRP is historically significant to the hobby, and preferably which is independent of Chaosium, Games Workshop, and anyone else directly linked to the material. By this I mean reviews and historical articles in publications such as Dragon, Escapist, etc. or, even better, in mainstream publications outside the hobby. Blogs of prominent industry people like Ken Rolston are also good, even though he worked for Avalon Hill on the RQ stuff.
If you find something, then you can either navigate the maze of templates and citation rules, or just post a reply here and I'll do that bit.
