Frustrated by the limitations of traditional textbooks and courses, Dr. Richard Baraniuk founded OpenStax (then Connexions) in 1999 at Rice University to provide authors and learners with an open space were they can share and freely adapt educational materials such as courses, books, and reports.

Today OpenStax CNX is a dynamic non-profit digital ecosystem serving millions of users per month in the delivery of educational content to improve learning outcomes.

There are tens of thousands of learning objects, called pages, that are organized into thousands of textbook-style books in a host of disciplines, all easily accessible online and downloadable to almost any device anywhere, anytime.  

Everything is available for free thanks to generous support from Rice University and several philanthropic organizations.

The content in OpenStax CNX comes in two formats:  modules, which are like small "knowledge chunks," and collections, which are groups of modules structured into books or course notes, or for other uses.  Open licensing allows for free use and reuse of all content.
