Information is nice, even I can take part and gain from it, physical property is always more difficult as it is always somewhere, when information can be anywhere, transferred, copied etc. very easily.
My suggestion is that you add information to Wikipedia Volvo 300 pages, this way everyone can check use and contribute, also as you may know Wikipedia is going to dvd-roms so this information would be possibly available to even where internet is not. I don't know if there was going to be even paper version of Wikipedia at some plans, but anyway it will be major source of information in future.
You know, at 1996 I was thinking about something similar like Wikipedia, too bad I did not had understanding what Internet will be back then, I might not be as poor as I'm now

I know Carpe Diem, but somehow I miss it always
I have Haynes, also v*dis, but these are only possible to be used as guidelines, because of copyrights, all drawing and materials should be self made to avoid legal issues.
I have been preparing hideously information from Solex carb and it's problems and how to solve them, however I have not yet solved all of my carb's problems and I'm bit out of money at the moment to continue, so it will be perhpas waiting to next spring to get completed.
