"How can cultural heritage institutions legally use the Internet to improve public access to the rich collections they hold?"
I've linked on anumberofoccasions to Peter Hirtle's thoughtful commentary on the Brodsky bill and related issues.

Read more about it (and download a PDF copy if you want) here.
