The Smithsonian has released the Best of Both Worlds: Museums, Libraries, and Archives in a Digital Age by G. Wayne Clough.
Here's an excerpt:
The review in this document illustrates how many cultural institutions have already found innovative applications for digital technology, but it is more than just a matter of "using." Digital technology will also change the basics of how these institutions work as we move forward. Collections will be shared across institutions through the linked data cloud; the public will participate in the creative activities of cultural institutions through engagement platforms; and informal education will merge with formal education. Cultural change is never easy, and while an institution might be able to avoid it for a while, this time it will be so big that no one will escape in the long run.
