It's not clear to me how much copyright they can place on the texts
Anything classical is PD, the translations can be copyright, but then they would not be at Perseus
(they didn't create them, and all(?) of the authors are long dead); but they can copyright the collection, I think.
If you deal with the texts individually, you can do what you like to any one of them. But you certainly couldn't mirrot their site w/o permission, or borrow their HTML, but who would want to?
