Number of journals using Open Journal Systems by year as of September 2015
These statistics show the number of journals using Open Journal Systems (OJS) available online in early September 2015.
A few notes:
- Each year ONLY shows journals with content published in that year.
- The numbers do not necessarily represent the adoption rate of OJS; rather, they represent the number of journals currently online, that have content with a publication date of a given year.
- URLs for installations were found by looking at the "referrer" addresses in the PKP website log (by default OJS links back to pkp.sfu.ca). As a result, some OJS journals are NOT reflected in these numbers.
- Counts are journals, not installations.
- Journals are counted for any given year if they have at least 10 articles published that year. Any journals not meeting this criteria are NOT included in these numbers.
- Journal content was found using the PKP Harvester using the OAI PMH (journals that disable OAI PMH will therefore not be counted).
