From: "Pennington, Buddy D." <[log in to unmask]> Date: Thu, 26 Jan 2012 23:17:00 +0000 I agree with that. Though, I think the short term loan pricing model would be an example of usage-based pricing for books. And libraries can utilize STL access without necessarily following up with the purchase.

Once an e-book is purchased through PDA, subsequent cost per use is either non-existent or nugatory (if you count a tiny fraction of ongoing hosting fees for e-book collections) . Fred W.
