Open Source Software

EDRLab is the home of Thorium Reader, the new Windows, MacOS and Linux reading app. EDRLab is also leading the development of three active projects of the Readium Foundation: Readium Mobile iOS, Readium Mobile Android and Readium Desktop on which Thorium is based. Each of these projects provides rock-solid, performant building blocks for navigating in EPUB publications, with full support of the EPUB 3 standard and the LCP DRM.

Support for people with print disabilities is a key part of our mission. We collaborate with European publishers and major inclusing organizations on the creation of a born-accessible ebook market. We also make sure that Readium projects take into account the assistive technologies used by visually-impaired users.
