Abstract:

Knowledge mapping of digital library (DL) reveals the semantic organization and the evolution of DL research topics. The article aims to identify the core topics and subtopics of DL research through knowledge mapping of the DL domain. The methodology comprises of a four-step research process, and two knowledge organization methods (classification and thesaurus building) were used. Knowledge mapping covering 21 core topics and 1,015 subtopics of DL research is created and provides a systematic overview of DL research during the last two decades (1990-2010). It can serve as a knowledge platform to guide and evaluate activities of DL research, education and practices.
