Open access
Bibliometrics
Definition. Open access is the free, immediate online availability of research outputs, combined with rights to reuse them.
Explanation
Suber describes open access as removing price and permission barriers to research (Suber, 2012). Gold, green and diamond models differ in who pays, and article processing charges create new inequities for authors in low-income settings.
