Open Journal Systems (OJS) is an open source software application for managing and publishing scholarly journals. Originally developed and released by Public Knowledge Project(PKP) in 2001 to improve access to research.
OJS is free and open source software. You are free to download, use, and modify it at no charge.
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
