Notable college art museums and collections?

Williams and Amherst both have very nice museums for their size Williams also has a couple of other excellent art museums nearby, while Amherst has the impressive Smith College museum nearby. I was impressed by the Amherst museum for a different reason - it is kept open to students every night until midnight as a study space. So you can do your homework under the gaze of a Winslow Homer, which is pretty cool.
