Open Textbook Library

The Open Textbook Library includes textbooks that are free to use and share, as well as those that are licensed to be freely adapted or changed with proper acknowledgment. The following are the requirements for adding new textbooks to the Open Textbook Library: All content must be released under an open license. Except for the CC ND (No Derivatives) component, we accept textbooks with GNU and Creative Commons (CC) licenses. The CC BY license is recommended. For additional information on choosing a license for your work, see Creative Commons. An entire textbook must be provided as a portable file (e.g. PDF, EPUB). It must be used in numerous higher education institutions or affiliated with one. It must be a unique textbook (not a derivative of another textbook). Modifications that reflect the needs or circumstances of a whole new audience may be an exception to this rule. For example, the textbook has been significantly altered such that it now applies to a new country, or profession, or has been translated into a new language. Significant changes to the original material will be required of authors or publishers.
