Open Journal Systems

Open Journal Systems (OJS) is an open source software application for managing and publishing scholarly journals. Originally developed and released by PKP in 2001 to improve access to research, it is the most widely used open source journal publishing platform in existence, with over 10,000 journals using it worldwide.

OJS is free and open source software released under the open source GPL v2 license, and you are free to download, use, and modify it at no charge.

PKP Publishing Services also offers a fee-based service which provides the installation and hosting of OJS, as well as performing daily backups of your data, applying security patches and upgrades, and priority answering your support questions. All revenue generated by the hosting service goes into developing PKP software and supporting the Public Knowledge Project. 

OJS is made freely available to journals worldwide for the purpose of making open access publishing a viable option for more journals, as open access can increase a journal’s readership as well as its contribution to the public good on a global scale (see PKP Publications).

“Scholars need the means to launch a new generation of journals committed to open access, and to help existing journals that elect to make the transition to open access…”
