Open access (OA) refers to freely available, digital, online information. Open access scholarly literature is free of charge and often carries less restrictive copyright and licensing barriers than traditionally published works, for both the users and the authors. OA is a newer form of publishing but many of these journals comply with well-established peer-review processes and maintain high publishing standards.

Many traditional publishers are now offering OA options e.g. Elsevier, Springer and Taylor and Francis.
