OpenStax College

OpenStax is a nonprofit educational initiative based at Rice University, and it’s our mission to give every student the tools they need to be successful in the classroom. Through our partnerships with philanthropic foundations and our alliance with other educational resource companies, we’re breaking down the most common barriers to learning. Because we believe that a well-educated society profits us all.

We publish high-quality, peer-reviewed, openly licensed college textbooks that are absolutely free online and low cost in print.
