Kolibri is a project of the Learning Equality project. It turns any computer into a library of offline learning content which is shared across the local network. So a laptop on a wireless router can serve content to any other computer which connects to it. Kolibri is easy to configure and can provide various levels of functionality – from a stand alone library on one computer to an institution wide system with user accounts for each student. It is completely free and open source and very easy to set up. https://learningequality.org/kolibri/
Our local Enactus team at La Sierra University is doing a similar project using thumb drives. They don’t have a website yet but may in the future.
