Abstract. This paper describes the results of a multi-level network analysis of web-citations among the 1,000 universities with the greatest presence on the world wide web. Using data from January 2011, it describes the web-citation network of the world’s universities and ascertains the antecedent factors that determine its structure. At the university level, the network is composed of ten groups, and the most central universities are mainly from the United States.
