Gold OA journals: all content is open access, and all authors must pay an Article Processing Charge (APC).
Hybrid journals: subscription-based journals, but individual authors have the option to pay an APC to have their article published open.
Diamond/Platinum OA journals: all articles are published open access, but with no APCs required from authors. These journals are typically funded by organizations, institutions, or other initiatives.
Green OA: also known as "self-archiving," this refers to the practice of making a version of the published article (usually the pre-publication manuscript) available open access in an institutional or disciplinary open access repository.
See the Library's page on Open Access and Discounts on APCs for APC-free publishing and APC waivers and discounts available for U of R corresponding authors.
