## What its pages say

Quoted word for word from openstax.org's own pages.

- In their own words: “OpenStax is a nonprofit education initiative of Rice University. We make free, peer-reviewed materials that millions of students use, and we study what actually helps them learn. OpenStax began as Connexions, a project built on a simple frustration: a textbook that cost $300 and taught the same thing as every other textbook on the shelf.” (https://openstax.org/about)
