The Digital Library Research Laboratory (DLRL) at Virginia Tech recently published the fourth and last of a series of books on Digital Libraries and the 5S (Societies, Scenarios, Spaces, Structures, Streams) approach.  Drs Edward Fox and Jonathan Leidig edited the book and Morgan & Claypool published it. The fourth book focused on digital libraries applications, and can be found here.  I co-authored the chapter on digital libraries applications in education with Yinlin Chen.

Digital libraries for educational resources  present many challenges including the participation and collaboration of community members. Monika Akbar et al addressed the problem by proposing DL 2.0, a model to integrate social knowledge to digital library content. But as educators move more  toward mixing and matching educational content to create compound learning objects, we need to create a whole new family of digital libraries services to interact with such resources. In the case of OpenDSA, visualizations and interactive exercises can be indexed as stand-alone resources in AlgoViz. But tutorials are created on demand and embed standalone visualizations and exercises. We should  index tutorials as well, and make them available to portals educational digital libraries. Which begs the question should we index raw source file or html output?
