What are the different types of open access publishing?
Answer
Although there are several different models of open accessing publishing, the following are the most common:
Diamond Open Access
Diamond open access is a scholarly publication model in which neither authors nor readers are charged fees. Diamond open access journals are often community-driven, led and owned by academics, and supported by scholarly or institutional initiatives.
Gold Open Access
Publications in Gold open access journals are made freely available to readers immediately upon publication. This model typically requires the author to pay an article processing charge (APC) to cover publishing costs.
Green Open Access
Green open access, also known as self-archiving, allows authors to make their work freely available by depositing a version of the publication in an open access repository. Typically, the author's accepted manuscript is archived after being published in a subscription-based journal. Publishers may impose an embargo period, delaying public access for a specified time.
Hybrid Open Access
A hybrid journal is a subscription journal in which some of the articles are open access. This model typically requires the author to pay an article processing charge (APC) to the publisher. If the author chooses not to pay the APC, the article remains behind a paywall and is accessible only to readers with an institutional subscription or those who purchase individual access.
