Open Textbook Library - The Open Textbook Library provides a growing catalog of free, peer-reviewed, and openly-licensed textbooks.

Open Textbook Library review process: We leave quality judgments to faculty with expertise in the subject area. When institutions join the Open Textbook Network, faculty are invited to review an open textbook. Around 60% of books in the Open Textbook Library have been reviewed. In addition, most open textbooks are reviewed during production, using systems implemented by the authors and publishers.

OER CommonsOER Commons offers a comprehensive infrastructure for curriculum experts and instructors at all levels to identify high-quality OER and collaborate around their adaptation, evaluation, and use to address the needs of teachers and learners.

The MERLOT collection consists of tens of thousands of discipline-specific learning materials, learning exercises, and Content Builder webpages, together with associated comments, and bookmark collections, all intended to enhance the teaching experience of using a learning material. All of these items have been contributed by the MERLOT member community, who have either authored the materials themselves, or who have discovered the materials, found them useful, and wished to share their enthusiasm for the materials with others in the teaching and learning community.

All the materials in MERLOT are reviewed for suitability for retention in the collection. Many undergo the more extensive "peer review" for which MERLOT is famous. MERLOT presents annual awards for various categories of materials added to or used in the collection. As described in Material Link Checking and Removal, all material URL's in the collection are reviewed frequently for stainability.
