Differing from the netLibrary model, a text can be used by more than one user at a time. Moreover, the subscription provides access to the entire Questia collection which changes with each newly added text. Although the netLibrary collection is increasing daily, any individual library's collection remains static unless the library pays for access to additional netLibrary titles. Questia's target market is individual subscribers, and they feel confident that students will be willing to pay the subscription fee out of their own pocket-money. No indications have been made about the size of the collection.
Users can search through and view the entire ebrary collection for free.
Fees are assessed on a per-use basis whenever the user prints or downloads a document. As with Questia, the fees are paid by the user, not by a library on behalf of its users. However, ebrary's business model does include a partnering role for libraries. Moreover, the library would receive regular statistics about their patrons' usage of the ebrary collection. In addition, libraries are encourage to submit their own unique digitzed collections for inclusion in ebrary.
