These are early days for the OLPC library exchange (in development); there is still a great deal of content that can be tried out on your XO out of the box, and a growing set of formats you can quickly create and remix.

Other release notes: Demo Notes (on how and what to demo), Hardware Release Notes (B1, B2), and Software Release Notes -- these are all useful for understanding the system and what is available. There are also general instructions on how to use the Sugar interface.

The software and interfaces for creation are still in alpha test stages, and we are just forming links to archives and repositories with their own metadata and format needs. Please refer to the OLPC Human Interface guidelines and Content guidelines for a vision of how we would like to see the content and interfaces on the laptops to develop, and what we want interfaces into existing platforms and collections to look like for XO users.

Efforts to date have focused on being able to read, write, and share materials in basic formats, and interfaces for children to editing and browsing these materials. Components still under development include a mesh view of who is working on what at any given moment, a reader/writer interface to editable material, and a distributed content store. While some of the early library is dedicated to static sample materials, to use in testing and as suggestions of what might be created, our goal is to help children and teachers create; and the best materials for the early library are those that expose their construction, or can be useful pieces in later work.
