Open Access (OA) refers to unrestricted online access to scholarly research publications along with the unrestricted usage of these publications in this digital and big-data era. This term and the concept of “Open Access” was first defined in three statements: the Budapest Open Access Initiative (2002), the Bethesda Statement on Open Access Publishing (2003), and the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities (2003). Publishing according to the Open Access model promotes science and education and benefits researchers and students because:
- Publications are immediately available online without subscription or price barriers;
- Publications are free to be archived in any personal, institutional, or governmental repositories;
- Publications are free to be distributed or reused without asking for permission;
- Publications receive higher visibility by worldwide audience;
- Publications receive more citations due to higher publicity.
