An author co-citation and bibliographic coupling analysis

This study continues a long history of author co-citation analysis (and, more recently, author bibliographic coupling analysis) of the intellectual structure of information science (IS) into the time period of 2006-2010. It finds that Web technologies continue to drive developments, especially for the research front, although perhaps more indirectly than before. A broadening of perspectives is visible in IS 2006-2010, where network science became influential and full text analysis methods complement traditional computer science influences. Research in the areas of h-index and mapping of science appears to have been highlights of IS 2006-2011. This study tests and confirms a forecast made previously by comparing knowledge base and research front findings for IS 2001-2005, which expected the IR systems and Webometrics specialties both to shrink in 20062010. A corresponding comparison of knowledge base and research front of IS 20062010 suggests a continuing decline of the IR systems specialty in the near future, but also a considerable (re-)growth of the Webometrics area after a period of decline from 1 Corresponding author This is a preprint of an article to be published in 2014 in Journal of The American Society for Information Science and Technology 2 2001-2005 to 2006-2010, the latter due perhaps in part to its contribution to an emerging Web Science.
