Nature Publishing Group goes Creative Commons: " In the continuing drive to make papers as accessible as possible, NPG is now introducing a 'creative commons' licence for the reuse of genome papers. The licence allows non-commercial publishers, however they might be defined, to reuse the pdf and html versions of the paper. In particular, users are free to copy, distribute, transmit and adapt the contribution, provided this is for non-commercial purposes, subject to the same or similar licence conditions and due attribution."link
