Specialists always have hegemony in their respective domains, and it is as if it were fear for an oligarchy of nerds or fans (there must be a Greco-phone word for government by freaks and geeks)—however benevolent or enlightened—or a turning-away from knowledgeable and vetted sources.

With just a few extra steps, one’s books can be viewed and saved on any tablet device, ready to be quoted, reworked and re-imagined. It would nicely personalize one's vacation itinerary, modularity, and saving the discovery for the trip and not the exhausted invention of the research and planning.
