Net Libray is a library that lends out digitalbooks. It treats a digital  like a  paperback copy. It charges libraries per book per copy and gives publishers a cut of  the total income.

From the consumer’s point of view，this means that if more than，Say, five people want the latest Danielle Steel romance novel，other people who request  that book will get a message saying the title can’t be found.

It’s a model many publishers seem to have embraced.

Kelle and some  other  librarians argue  for  the  e-book  vision  set forth by E-Brary. E-Brary is starting a service that lets us users read books for free.
