Josh Marshall at Talking Points Memo has an interesting post about the rich resources available on the internet. He also provides several examples such as sites that give one access to: the Codex Sinaiticus, historical maps, photograph collections, the papers of Frederick Douglass, etc.
He also discusses the problems faced by those who provide these digitized resources.
All in all, a good read and a reminder that not everything on the web is simply garbage.
