I assume most of you get CRL News, but just in case you don't, there's an article in the most recent issue about UCLA's experience with trying to expose hidden collections. And there's another article "Engaging undergraduates in special collections through English composition: collaborating for student success." Both are available here: http://www.ala.org/ala/acrl/acrlpubs/crlnews/backissues2008/june08/june1.cfm
