Abstract: The field of digital libraries (DLs) coalesced in 1994: the first
digital library conferences were held that year, awareness of the World
Wide Web was accelerating, and the National Science Foundation awarded $24
Million (US) for the Digital Library Initiative (DLI). In this paper we
examine the state of the DL domain after a decade of activity by applying
social network analysis to the co-authorship network of the past ACM, IEEE,
and joint ACM/IEEE digital library conferences. We base our analysis on a
common binary undirectional network model to represent the co-authorship
network, and from it we extract several established network measures. We
also introduce a weighted directional network model to represent the co-
authorship network, for which we define AuthorRank as an indicator of the
impact of an individual author in the network. The results are validated
against conference program committee members in the same period. The
results show clear advantages of PageRank and AuthorRank over degree,
closeness and betweenness centrality metrics. We also investigate the
amount and nature of international participation in Joint Conference on
Digital Libraries (JCDL). (c) 2005 Elsevier Ltd. All rights reserved.
