This map provides the international distribution of journals known to be using Open Journal Systems to manage and/or publish their contents as of January 2012. Journals using OJS are invited to register with the PKP site to help update these figures.

The map is based on the identifiable location of the server that is hosting the journal's installation of OJS (unless we know the journal to being a service elsewhere), and may not reflect the actual location of the journal editor or publisher.
