New e-book format already in hands of publishers
Amazon may be beta testing its new Kindle e-book format with selected publishers. The new format, referred to by Amazon as Kindle Format 8 (KF8), provides support for HTML5-based content. The Digital Reader, which revealed the testing, also reports that a number of graphic novels may already be available in the format and readable by the new Kindle Fire.
Amazon hasn't confirmed the details or said how soon it planned to fully adopt KF8.
