Readium

Readium is an open-source software project that enables digital books, especially EPUB files, to be read smoothly on various devices and platforms. It acts like a bridge, allowing e-books to be displayed consistently across browsers, apps, and e-readers. Think of it as a universal reader engine that helps publishers, developers, and readers access and enjoy digital books with good formatting, digital rights management, and accessibility features. Essentially, Readium makes electronic reading more flexible, compatible, and user-friendly without requiring proprietary software.
