Editoria

Online production tool for monograph publishing.
Editoria is the open source, browser-based books production tool developed by the Collaborative Knowledge Foundation (Coko) in collaboration with University of California Press and California Digital Library. Editoria is powerful in its ability to save presses time and cost in workflow thanks to collaboration tools, and automated typesetting.
Editoria is 100% reliant on its community for support and sustenance. This means that the answer to most questions is that everything is possible, if the community identifies a problem and prioritizes solving it.
