Researchers at Penn State University have been piloting a technology that allows faculty ( and students ) to build e - textbooks algorithmically using keywords to gather together materials from open resources . The tool , called BBookX , lets users build textbooks chapter by chapter , adding content by using keywords to find relevant resources , which can then be organised and searched by the user . Keywords are used to find an initial set of resources ; adding the most relevant resources to a chapter then allows the user to refine searches for additional materials . BBookX: Users can rearrange the materials within a chapter or reorganise entire chapters as they go , via a drag - and - drag interface .
