Science Commons is a project of the non profit corporation Creative Commons.
Quoting about What is Science Commons?
“We are a branch of the nonprofit Creative Commons, devoted to easing unnecessary barriers to the flow of scientific knowledge and technical information. We work to encourage scientific innovation by making it easier for scientists, universities, and enterprises to share scientific literature, data, and materials. Our goal is to encourage stakeholders to create through standardized licenses and other means areas of free access and inquiry; a science commons built out of private agreements, not imposed from above.”
Creative Commons offers a flexible range of protections and freedoms for authors and artists. Yahoo Search also offered the new Yahoo Creative Commons Search Beta. This is a unique application of the some rights reserved philosophy to Science.
