I think library is a set of utilities to reach a goal (for example, sockets, cryptography, etc). Framework is library + RUNTIME EINVIRONNEMENT. For example, ASP.NET is a framework: it accepts HTTP requests, create page object, invoke lyfe cicle events, etc. Framework does all this, you write a bit of code which will be run at a specific time of the life cycle of current request!

Anyway, very interestering question!
