Open Access or OA is a digital publishing model in which a work is made freely available to the end user. The author of the work retains their copyright and right of attribution, but makes it freely available for download, copy and distribution. Authors may also elect to allow users of their work to modify the work or use it as the basis for a new work.
In the academic world, open access means free access to research results and research data, as well as use and adaptation of open educational resources or OERs. Open access benefits students by reducing the cost of course materials. Benefits to the research community include breaking down socio-economic barriers to access, wider distribution of research, and increased recognition for researchers.
