Initiative aims to break science's citation paywall : Nature News & Comment

"The Initiative for Open Citations (I4OC) aims to allow anyone to access science papers’ reference lists and to build analytical services on top of that raw data. Started last year by the Wikimedia Foundation in San Francisco, California and five other partner organizations, I4OC announced at its official launch on 6 April that 29 organizations, including some of the world’s largest scientific publishers, have now agreed to openly release citation data."
