If the graphs you are using were gathered by UbiCrawler, please acknowledge the usage of UbiCrawler by quoting the following paper:  "UbiCrawler: A Scalable Fully Distributed Web Crawler", Paolo Boldi, Bruno Codenotti, Massimo Santini, and Sebastiano Vigna, Software: Practice & Experience, 2004, vol 34, no. 8, pp. 711--726 LAW/webbase-2001 This graph has been obtained from the 2001 crawl performed by the WebBase crawler. The data provided by WebBase has been filtered to eliminate invalid links and to normalise URLs. The experiments reported in reports "The WebGraph Framework I: Compression Techniques" and "Codes for the World-Wide Web", (both at http://law.di.unimi.it/ ) are based on this graph and on uk-2002. Note that for historical reasons the URLs of this graph are coded in ISO-8859-1. For additional graph properties and statistics, including node labels, see http://law.di.unimi.it/webdata/webbase-2001
