OpenStax is a nonprofit organization and initiative that provides free, high-quality, open-access textbooks and educational resources for college and high school courses. The organization was launched in 2012 by Rice University and has since become a leading provider of open educational resources (OER).

OpenStax textbooks cover a wide range of subjects, including mathematics, science, social sciences, the humanities, and business. These textbooks are created by expert authors and undergo a rigorous peer review process to ensure their quality and accuracy. The materials are designed to align with standard college and AP (Advanced Placement) courses, making them suitable for both college students and advanced high school students.

One of the main goals of OpenStax is to address the issue of rising textbook costs and make education more affordable and accessible. By offering free digital versions of textbooks, OpenStax helps students save money on expensive traditional textbooks. Additionally, print copies of the textbooks are available for purchase at a fraction of the cost of commercial textbooks.

OpenStax textbooks are available in multiple formats, including PDF, web-based versions, and EPUB formats for e-readers. They can be downloaded directly from the OpenStax website or accessed through various online platforms and learning management systems.

In addition to textbooks, OpenStax also provides supplementary resources such as online homework systems, assessment tools, and instructor resources to support teaching and learning. The organization actively encourages educators to customize and adapt the materials to suit their specific needs, making it a flexible resource for instructors.
