Number of journals using Open Journal Systems
Notes: This map shows the journals using Open Journal Systems (OJS) available online sometime in the last 30 days. Each year ONLY shows journals with content published in that year. The numbers do not represent the rate of adoption of OJS (many journals only upload back issues without publishing ANY current content, skip a year, or go offline).
- 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.
- Journals are counted for any given year if they have at least 10 articles published that year. Installations are counted if there is at least one journal in that install that meets the criteria. Any journals not meeting these criteria are NOT included in these numbers.
- Journal content was found using the PKP Harvester using the OAI PMH.
