Open access (OA) options will vary depending on the journal and publisher. The most common OA models in scholarly journal publishing are green, gold, diamond/platinum, and hybrid:
- Green: The author-accepted manuscript is deposited into an open repository or the author’s personal website.
- Gold: An article-processing charge (APC) is paid by an author or funder, or a transformative agreement is in place between the author’s institution and the publisher, to cover the costs of publishing in a fully open access journal.
- Diamond/Platinum: Full journal content is published OA without APCs or reader fees. Funding comes from external sources such as advertising, philanthropy, governments, or academic institutions.
- Hybrid: A subscription-based journal offers the option to publish individual articles gold OA with payment of article-processing charges.
