Don't know if it has been mentioned, but you might also want to contact:

        213.625.0404 (voice)
                1770 (fax)

I'd recommend especially contacting the head of their Photographic and
Moving Image Archive, Karen Ishizuka, at above phone #, ext. 450. She was
very involved with an exhibit on internment two years ago and was also on a
panel about this at the Society of American Archivists conference, 1993.
