"What do we know about Google Editions? The answer, unfortunately, is not a heckuva lot." (Eric Freese for DigitalBookWorld 7/19/10.)
Stephen Abrams (late of Sirsi, now at Gale) is positive, but Clint Boulton at Google Watch is not.
I like the idea of device independence and the scale of the offerings, but so far everything I hear is aimed at the individual consumer market. No place for libraries until we see the institutional subscriptions that come out of the Google Book Search Settlement.
