What is Green Open Access?

Green Open Access is a publishing model in which an article is made freely accessible online without the help of a publisher. This can be done before, during or after an article is officially published.

Green Open Access

Green versus Gold Open Access

The main difference between Green- and Gold Open Access is that in Gold Open Access the open access version of the article is available directly at the publisher's source page, instead of elsewhere online.

Green Literature

Green Open Access articles are predominantly grey literatures or pre-prints deposited in an institutional or scientific repository. These articles do not necessarily undergo peer review or editorial process. However, also a postprint -a peer-reviewed version of a an article that only misses the publisher's layout- that is available online other than at the publisher’s original source page, such as at Academia the OALibrary, is considered Green Open Access.
