All revenue generated by the hosting service goes into developing PKP software and supporting the Public Knowledge Project. 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. 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). This all-new version has been rethought from the ground up: it’s got an all-new design, delightful new interactions, and powerful new features.
You are free to download, use, and modify it at no charge. Things is the award-winning personal task manager that helps you achieve your goals. OJS is free and open source software released under the open source GPL v2 license.
