Open access is a publishing model whereby scholarly journals, articles, and books are published online with no access restrictions immediately upon publication, and with little to no restrictions on reuse of the material. Learn more.
Open access (OA) is achieved through two primary methods:
Green open access: OA repositories such as NIH's PubMed Central and the University of California's eScholarship
provide a platform where authors may deposit their previously published
articles. No payment is required for green OA since the deposit is in
accordance with publishers' self-archiving policies, with funding agency policies, or with institutional policies such as the UCSF OA Policy.
Gold open access. Peer-reviewed OA journals (and books) operate the same as traditional peer-reviewed publications, except that the publication costs are borne by either the author, funder, or other entity.
