I don't think copyright is involved in transporting files between buildings, since both buildings belong to the LC. A team I work with actually raised the issue of copyright some time ago, and I think in general copyright issues are still being worked out, at least in the area of digital rights management. I'm part of an IT team, but if you're really interested, I'd be glad to forward this question to someone who can answer it better than I and pass along the answer.

What is the status of the copyright issues raised by sending the digital
files from Culpepper to the Madison Building?
