This article investigates the extent to which citation and publication patterns differ between men and women in the international relations~IR! literature+ Using data from the Teaching, Research, and International Policy project on peerreviewed publications between 1980 and 2006, we show that women are systematically cited less than men after controlling for a large number of variables including year of publication, venue of publication, substantive focus, theoretical perspective, methodology, tenure status, and institutional affiliation+ These results are robust to a variety of modeling choices+ We then turn to network analysis to investigate the extent to which the gender of an article's author affects that article's relative centrality in the network of citations between papers in our sample+ Articles authored by women are systematically less central than articles authored by men, all else equal+ This is likely because~1! women tend to cite themselves less than men, and~2! men~who make up a disproportionate share of IR scholars! tend to cite men more than women+ This is the first study in political science to reveal significant gender differences in citation patterns and is especially meaningful because citation counts are increasingly used as a key measure of research's quality and impact+ In this article we use the term gender rather than sex to refer to our male0female variable+ We realize that the two terms are not synonymous, nor is gender dichotomous+ We prefer to use the term gender because the coding of the author of a publication is based heavily on the pronouns an author uses to identify him-or herself+ The result, however, is that we are unable to include a category for transgendered scholars+ We regret this+ Still, because of the fact that transgendered individuals make up such a small proportion of the total population of IR scholars, any analysis of citation patterns of articles authored by transgendered individuals would be unreliable at best+ International Organization 67, Fall 2013, pp+ 889-922
