Additionally, so much of the internet is ephemeral, compared to the content that students or researchers would have been photocopying when Umberto Eco wrote the piece that's quoted in the article. For this reason, if I find an interesting article/page/whatever, I tend to save a local copy even if I don't know when or if I'll read it. It might not be online anymore when it turns out to be useful.
