Open access (OA) content is shared freely on the internet, and ranges from publicly available content (e.g. self-archived articles of faculty) to that which can be fully revised and re-shared (e.g. OA textbooks). OA works are usually marked with a license (often a Creative Commons license), showing what users can do with the work.
The Directory of Open Access Journals (DOAJ) aims to be comprehensive and cover all open access scientific and scholarly journals that use a quality control system to guarantee content.
Scholars have created many open access textbooks, supplemental materials, courses, and more that can be used in teaching. To find out more about these resources, visit the Open Educational Resources guide.
