The Readium Projects primary goal is to provide rock-solid, performant building blocks and applications for EPUB3 publications.
There are two parts to ReadiumJS:
• A Readium Chrome Extension which is available from the Chrome Web Store. It is one of the most full-featured EPUB 3 Reading Systems available.
• A cross-browser implementation known as the CloudReader.
The Readium SDK project is developing a compact, performant EPUB 3 rendering engine optimized for use in native apps for tablets and other devices. The Readium SDK Core C++ library with platform wrappers implementations where appropriate.
THe SDK is available for both open-source and commercial use. Details of the licensing is available here
The Readium Foundation is developing a DRM library, Licensed Content Protection (LCP) which can be used with the Readium SDK to build DRM-enabled clients as well as server-side components. Readium SDK will not require use of Readium LCP, which will be separately licensed to interested parties.
Readium is an open-source project and extends its thanks to the following organizations for supporting our open-source development.
