Good question:
What exactly does a page do (officially, that is)?
What IS a "page"?
In 1981 I was in a band that played the Page's Prom. I was 21 - lots of good-looking females. This has pretty much nothing to do with this thread - it is just my "page story"
"What exactly does a page do (officially, that is)?"
Congressional staff gofers.
A college friend did that job one summer. He said they partied like hell, smoked dope at lunch and generally had a large time of themselves.

They're more or less "go-fer's", and have been around for as long as Congress has been around. In the electronic age, they're not needed. IMHO.
