Interesting essay over at sshhh This is a Working Library:

"The promise of ebooks (or, one promise, anyway), is their inherent connectedness. On a whim or the turn of a phrase, I can leap from Shakespeare to Soyinka, finding similarities that didn’t exist before, or else existed but were yet unknown. In exchange for the loss of continuity, I gain a new space for metaphors: no longer within the texts, but between them."
