I just got reminded that I'm hosting this ... www.ihpva.org recently gained a scanned and indexed copy of their Human Power journal thanks to a bunch of people that wanted it. Likewise www.ata.org.au have been persuaded to offer their magazine on CD updated every year or two. We're hopefully moving to offering online subscriptions (ideally the way www.homepower.com do). So with formal publications, no matter how small, it's likely that if you scan and OCR it people will love you for it.
