Open textbooks are free, online learning materials with Creative Commons licenses. Many of the collections will have links to the same books, but each will have a particular focus, and items you can't find in other collections.
OER repositories contain more than just open textbooks. All content featured within these pages is free but usage rights vary. Materials in these repositories are released under a Creative Commons license while some are in the public domain.
The Mason OER Metafinder helps you find Open Educational Resources by searching across 22 different sources of open educational materials.
The Library subscribes to databases which contain e-books, e-journals, images, videos, and more. These resources are free to use by LCC students, faculty, and staff. However, they do not contain the copyright permissions to allow for customization, re-use, remix, or redistribution in the same way as open educational resources. Although online library resources are not "open," they are resources you can make available at zero cost to your students.
