If you publish results based on this graph, please quote the references suggested in the dataset page.

LiveJournal is a virtual-community social site started in 1999: nodes are users and there is an arc from x to y if x registered y among his friends. It is not necessary to ask y permission, so the graph is directed). This graph is the snapshot used by Flavio Chierichetti, Ravi Kumar, Silvio Lattanzi, Michael Mitzenmacher, Alessandro Panconesi, and Prabhakar Raghavan in “On compressing social networks”, KDD '09: Proceedings of the 15th ACM SIGKDD international conference on Knowledge discovery and data mining, pages 219−228, 2009, ACM press, and was kindly provided by the authors.
