OpenStax is a nonprofit educational initiative of Rice University dedicated to making high-quality learning materials more accessible and affordable.
The platform publishes free, peer-reviewed, openly licensed textbooks for high school and college-level education. Its library covers subjects such as mathematics, biology, chemistry, physics, economics, business, and social sciences.
Most textbooks can be read online or downloaded as PDF files without a subscription. The materials are designed for students, instructors, and educational institutions looking for reliable alternatives to traditional expensive textbooks.
OpenStax also provides additional teaching and learning resources to support classroom instruction and student understanding.
