the og scan of book of kells was done by a Swiss publisher in the early 90s. since you can't copyright a scan, and the book itself is in public domain, anyone can then take the scans (if they can get hands on the high dpi originals or whatever, or do a high dpi scan of the reproduction) and publish them as whatever they want. "the complete encyclopedia of human knowledge (only $99.99 if you call now)" "the illuminated authoritative book of kells (comes with your own one of a kind handmade Irish cross)" etc. you can get the scans themselves (afaiu its at matching dpi, if not the same format) from a 2006 trinity college dvd of book of kells.
the op is an announcement of the completed rescan effort, with modern technologies and modern dpis. with a companion iPad app and a website that have consumer grade renditions of those modern research grade scans.
