The textbook price increases were once thought to be a genius way to increase profit margins. However like all goods and services, even those with the most inelastic demand curves have a point at which people will begin to substitute them for another good.

The long run solution is subscription - access to all the content required by the students at an affordable monthly price.

We are working with Oxford University Press, Taylor & Francis and Cambridge University Press to achieve exactly that. Our challenge is convincing publishers to provide the necessary content under a subscription model
