Instruction sources (links) is something I have planned to add to the Matrix section, as it is a common question from fans, new and old.

I did a google search recently of "Transformers Instructions", and found some fansites that were archiving scans, back before Hasbro started to. I agree that it would be good for Hasbro to have an archive of old instructions, or at least attempt to cover at least all "moulds" on their site, with searches of redecos leading to the one set of original instructions.
