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

This dataset was made public by the Federal Energy Regulatory Commission during its investigations: it is a partially anonymised corpus of e-mail messages exchanged by some Enron employees (mostly part of the senior management). We turned this dataset into a directed graph, whose nodes represent people and with an arc from x to y whenever y was the recipient of (at least) a message sent by x.
