But an initial review of that library left some unimpressed, both by the prices and the offerings. Many of the books are public-domain titles that are available free through Project Gutenberg — which GTL links in its press materials as the source of e-books — but that cost anywhere from $2.99 (Moby-Dick) to $11.99 (The Federalist Papers), all the way up to $14.99 (Joseph Conrad's The Rescue). Many more recent titles also are priced far higher than the same Kindle e-books. For instance, Stephen King's prison tome, The Green Mile, costs 66 percent more on prison tablets than out in the free world.
