I know there are a lot of people over 60 in this country who are resistant to the internet, but if there's one sure-fire way to get them interested in the web it's the 1911 census. The archives of nine counties are now online and the other 23 counties will be added by the end of this summer.
I've seen the reaction a few times already. It isn't just the raw data that's interesting, but the fact that you can view the actual form that was filled in back in April 1911. When today's elderly person sees a parent's name and, often, a grandparent's hand-writing they're hooked.
Public libraries should advertise the 1911 census on the internet and encourage older people to try searching the records.
