Broadband eBooks (BBeB)

The digital book format originally used by Sony Corporation. It is a proprietary format, but some reader software for general-purpose computers, particularly under GNU/Linux (for example, Calibre's internal viewer[2]), have the capability to read it. The LRX file extension represents a DRM encrypted eBook. More recently, Sony has converted its books from BBeB to EPUB and is now issuing new titles in EPUB.
