Open access citation advantage

Open access citation advantage (OACA) is a type of bias whereby scholars tend to cite academic journals with open access (OA)—that is, journals that make their full text available on the Internet without charge and not behind a paywall—in preference to toll-access publications. The concept was introduced under the name FUTON bias ("full text on the net") by UK medical researcher Reinhard Wentz in a letter to The Lancet in 2002.
