The Hammer Museum is on the campus of UCLA, so I imagine that a majority of folks haven’t been able to view the collection. I was able to visit the Hammer as part of a tour of LA Area museums (which is a blog for another time but also a totally worthwhile trip). The Hammer recently received a grant to digitize some of their archives and exhibits.
The first exhibit is an examination of African American art in Los Angeles during the 1960s. The art from the exhibit is online, as are the lectures, essays, and presentations that surrounded the exhibit. They are planning on two more exhibits with the same supporting information as well.
This is a good example of the rise of digital exhibits in the museum and library world– we can’t travel as often as we’d like or visit all the museums we may want to, and the rise of these digital archives allows us to see more exhibits, view more art, and hopefully experience more than we otherwise might have.
