Open Access
Open access resources are "digital, online, free of charge, and free of most copyright and licensing restrictions." (Peter Suber's Open Access Overview)
In academic journal publishing, you're likely to come across the following OA models:
- Gold OA, where the author publishes in an open access journal. Depending on the journal policy, the author may have to pay an article processing charge (APC);
- Hybrid, where the author pays an APC to publish their article open access in a subscription journal; and
- Green OA, where the author makes a version of their article open access by self-archiving in a repository. For more information about Green OA, check out the "Pre-prints, Post-prints, and Publisher PDFs" box on the Sharing Your Research tab.
