Information Infrastructure: Not Really so Novel, After All

I apologize for the lateness of this post, like half of the rest of Madison, I came down with the flu this week, and am only just now approaching coherence.

One really short question this week: John refers to information infrastructure as being a novel concept. Perhaps it was, at that time, a novel concept within mass communication, but it's at the center of many studies in LIS. My question is, of all the pieces of the infrastructure John has named, what are some key pieces that he leaves out? And how key is the internet in the modern infrastructure?
