What Is Open Access?
Open access (OA) means making research publications freely available, benefiting anyone from reading and using the research. Open Access initiatives seek to remove barriers such as "paywalls" and make free research articles and other works easy to find and read.
Open access is part of a wider ‘open’ movement to encourage the free exchange of knowledge and resources to widen access and encourage creativity (Fox Valley Technical Resources).
