• The NSDL as a testbed for digital library learning research

      Coleman, Anita Sundaram; Su, Youfen; Burrows, Howard (Project Kaleidoscope, 2004)
      This article discusses the National Science Digital Library (NSDL), a National Science Foundation (NSF) project as an infrastructure or test bed for large-scale and integrated research at the intersections of digital libraries and digital learning. An aggregated evaluation service, modelled on the Text Retrieval Conferences (TREC) and an evaluation materials clearinghouse are starting points for solving the digital learning problem in digital libraries research.
