I don't have the answer, but the best museum website list I have found
is the Museum Computer Network's, found at
http://world.std.com/~mcn/resources.html - Its a great bookmark.
What, I would like to know is if their are other large private and/or
foundation art collection website such as ours -- any addresses would be
helpful. This type of site can be a great help to museum curators and
directors.
Thanks
