What information is available?
Open access to publications refers to the possibility to freely access research publications. These are divided into:
- Gold Open Access: research outputs made open access by the publisher; journal publications are freely available on the journal website,
- Green Open Access: research outputs that are not made open access by the publisher, but that the author independently deposits in an open access repository.
On this page you will find indicators on how the policies of journals and funding agencies favour open access, and the percentage of publications (green and gold) actually available through open access.
The indicators cover bibliometric data on publications, as well as data on funders' and journals' policies. Indicators and case studies will be updated over time.
You can download the chart and its data through the dedicated menu within each chart (top right of the image).
For more information, see the methodology report.

Additional indicators
There are many other indicators to monitor open access, such as:
- Number of preprints
- Articles published before peer review
- Surveys on attitudes of researchers towards Open Access by 101 innovations, Taylor and Francis, and Nature Publishing Group
