Open Access (OA) means unrestricted online access to articles published in scholarly journals.
When talking about Open Access, we say there are two ways to Open Access: the green road and the golden road.
Authors publish in a journal, then self-archive their article in institutional or subject repositories.
Authors publish in Open Access journals that give immediate access to all articles on a publisher's website. A publishing fee may be charged to the author (or the author's institution). Hybrid journals provide golden Open Access only for those articles for which their authors have paid a publishing fee.
Open Access journals
The Directory of Open Access Journals (DOAJ) provides a complete survey of Open Access journals. DOAJ includes Open Access scientific and scholarly journals that use appropriate systems to guarantee the quality of their content. Public Library of Science (PLoS) and BioMed Central are well-known Open Access publishers.
FRITT free journals from UiO represent a service for scientific groups and researchers at the University of Oslo who wish to establish peer-reviewed Open Access journals or convert existing journals to Open Access.
