C&RL just placed my latest article on their pre-print server. It will be published in the Spring 2009 issue of the journal. I originally came across the USOE policy while writing my dissertation, specifically when I got hold of Julius Marke's book, Copyright and Intellectual Property. There are obvious links to the current NIH Public Access Policy and I thought a historical comparison might be interesting. Let me know what you think.
By the way, I am really glad to see this open access pre-print server. ACRL: livin' the OA dream!
