Open Access Resouces

Open Access refers to resources that are available for viewing or use free of charge. Open Access is not identical with Public Domain, and the copyright of Open Access is mostly retained by the creators.

Open Access resources are excellent materials to supplement other online library materials. Many scholarly and peer-reviewed journals have opened their previous issues as open access, and some journals have converted to open access for all issues partially or entirely.

While most of the Open Access resources are still under copyright by their creators, academic or educational use is generally allowed without permission. For educators, open-access materials can usually be linked from an online syllabus or reading list, even when copying is not permitted. However, it is recommended to make sure to check the copyright or permissions statement before use at all times.
