OpenStax CNX

OpenStax CNX was Founded as Connexions in 1999 by Richard Baraniuk. OpenStax CNX is based on the philosophy that scholarly and educational content can and should be shared, re-used and recombined, interconnected and continually enriched. As such, it was one of the first Open Educational Resources (OER) initiatives along with projects such as MIT OpenCourseWare and the Public Library of Science.
