Here's the Communications Act of 1934, which contains Title II: http://transition.fcc.gov/Reports/1934new.pdf

Here's the Telecommunications Act of 1996, which modifies Title II: http://www.gpo.gov/fdsys/pkg/PLAW-104publ104/pdf/PLAW-104pub...

Got to warn you, it's not light reading.

I haven't been able to find something that explains Title II in a relatively neutral fashion. In short, proponents of classifying broadband as a Title II utility say "the FCC can ignore and not enforce the onerous portions not related to net neutrality", while opponents say "the FCC can ignore and not enforce the onerous portions not related to net neutrality, but there's no guarantee that they will, and that's a lot of power to hand over to the government for the indefinite future."
