Aspects of that experience and how it might affect the user's interactions with the DL are discussed in this module. In addition, users continuously make decisions about and evaluations of the materials retrieved from a DL, relative to their information needs. Relevance judgments, and their relationship to the user's information needs, are discussed in this module.12 pagesapplication/pdfen-USIn CopyrightComputer scienceDigital librariesInformation needsUser interactionLearning objecthttp://curric.dlib.vt.edu/modDev/modules/DL_6-a_2009-10-07.pdf
