Open access (OA) journals area unit academic journals that area unit obtainable on-line to the reader "without money, legal, or technical barriers aside from those indivisible from gaining access to the net itself." They take away worth barriers (e.g. pay-per-view fees,subscription, licensing fees) and most permission barriers (e.g. copyright and licensing restrictions).
Where as open access journals area unit freely obtainable to the reader, there area unit still prices related to the publication and production of such journals. Some area unit backed, and a few need payment on behalf of the authors.
