Available to all
Open Access is open and free for everyone. It makes available research results to anyone with an internet connection rather than keeping those results hidden behind subscription paid access to journals.
The focus of Open Access is to provide access to peer reviewed research articles.
You can check the peer-reviewed status of an Open Access (OA) journal by searching the DOAJ (Directory of Open Access Journals)
OA affects citation rates
Recent studies have begun to show that open access increases impact. View a bibliography of studies about the effect of open access and downloads ('hits') on citation impact.
The Benefits of Open Access (OA) publishing
Publically funded research is made available to the public.
Allows research results to be shared more easily and quickly, and by a wider audience.
Brings increased visibility of researcher's work and greater impact.
Allows research institutions to showcase their research output.
Open access publishing has become a global trend. Many universities, research institutes and funding bodies have introduced their open access mandates or policies that require or recommend their faculty and researchers to make their scholarly output available for open access.
ROARMAP (Registry of Open Access Repositories Mandatory Archiving Policies) is a voluntary self-registering service that provides information on the universities, research centers, and more that have a mandate to make research OA.
