Three stories from the last few days are importantly related. When Google added EPUB support to their public-domain book downloads, it was a good move for open access. EPUB is an international, open standard supported by many brands of e-book readers. Sony—which is about to file an amicus brief supporting the settlement—uses EPUB on its Reader. Meanwhile, Amazon—which is about to file objections—uses its own, proprietary file format on the Kindle.
All three companies will have legitimate legal points to make, of course, but one mustn’t neglect the commercial power politics behind their choice of positions.
