When my access to the net was super slow I downloaded an offline hyperlinked concise version of Wikipedia (mostly for developing countries).

This offline version for me felt a pretty important thing - you could classify that as a hyperlinked 'document' I guess. This potted history of everything that had gone on so far reminded me of the Hitchhiker's Guide to the Galaxy - thankfully without any examples of Vogon 'Poetry'.

Here's a bit of trivia for you. Back in the early days. I used to buy magazines to learn about interesting sites (before search engines maybe?) The guy who wrote 'Hitchhiker's' (Douglas Adams, who was very into the 'net) came up with what I can only describe as a prototype to what we know as Wikipedia now. The site was h2g2 dot something or other.

Grandpa will shut up and go back to sleep now...
