Open Journal Systems (OJS) is the world's most widely used open-source journal management and publishing system. Developed by the Public Knowledge Project (PKP), OJS can be downloaded and installed locally but is also commonly hosted by library or institutional IT services. OJS manages workflow for the entire refereed publishing process, providing a common model for the operational processes of a peer-reviewed journal. Through the PKP, OJS also connects with myriad indexing, identification, discoverability, and preservation services.
