This paper examines the co-authorship network of the digital library (DL) research community, focusing on the ACM, IEEE, and joint ACM/IEEE digital library conferences from 1994 to 2004. The authors apply social network analysis to understand the structure of collaborations within the DL field. They introduce a weighted directional network model and define *AuthorRank* as a measure of an author's impact in the network. The results are validated against conference program committee members, showing that AuthorRank and PageRank outperform traditional centrality metrics like degree, closeness, and betweenness centrality. The study also investigates international participation in the Joint Conference on Digital Libraries (JCDL). The findings highlight the evolving nature of the DL field, its multidisciplinary nature, and the importance of collaboration in shaping the community's structure and influence.This paper examines the co-authorship network of the digital library (DL) research community, focusing on the ACM, IEEE, and joint ACM/IEEE digital library conferences from 1994 to 2004.
