From the press release:
Infinity Publishing, a pioneer in author-originated book publishing, today announced the introduction of a comprehensive eBook publishing program for published authors and aspiring writers.Infinity's converted eBooks come with a quality guarantee that allows the author to approve a physical proof prior to their title being entered into marketplace distribution. Infinity eBooks will be compatible with Amazon's Kindle, Apple's iPad, Sony's eReader, HP's iSlat, Barnes and Noble's nook, Borders' soon-to-be-released eReader, Google's upcoming eBook platform, and other future hand-held electronic reading devices. This is a significant quality guarantee in the currently unstable eBooks conversion market, where formatting glitches and other imperfections are common.
Infinity Publishing revolutionized the category of self-publishing by providing "author-originated book publishing" services for authors. Infinity now has more than 4,000 active authors who have collectively published more than 6,000 titles with the company.
Check out that second paragraph. They're promising a paper proof for a digital book. Can someone explain that to me?
