CCNY OER

The Open Textbook Library is a comprehensive referatory that points to open textbooks by a variety of authors and publishers. The Open Textbook Library defines open textbooks as textbooks that have been funded, published, and licensed to be freely used, adapted, and distributed.

OpenStax, part of Rice University, published high-quality, peer-reviewed, openly licensed college textbooks that are absolutely free online and low cost in print.

Internet Archive is a non-profit library of millions of free books, movies, software, music, websites, and more.

The primary aim of DOAB is to increase discoverability of Open Access books. The directory is open to all publishers who publish academic, peer reviewed books in Open Access and should contain as many books as possible, provided that these publications are in Open Access and meet academic standards.

HathiTrust Digital Library is a digital preservation repository and highly functional access platform. HathiTrust provides long-term preservation and access services to digitized content from a variety of sources, including Google, the Internet Archive, Microsoft, and in-house member institution initiatives.

The LibreTexts mission is to unite students, faculty and scholars in a cooperative effort to develop an easy-to-use online platform for the construction, customization, and dissemination of open educational resources (OER) to reduce the burdens of unreasonable textbook costs to students and society.
