In this model, often called print plus , a publisher requires a school to pay for its print subscriptions and, for a typical surcharge of 15 percent, delivers the titles online. But some publishers, such as the American Chemical Society, take a hard line when customers want to cancel print subscriptions. Publishers like this model because it guarantees sufficient revenues to fund the transition to electronic products. Libraries complain that this system punishes the best customers. The final model is the simultaneous users license , which allows a maximum number of people to be online at the same time.
Customers know very soon if too much or too little access was ordered.
