This article introduces a web-based tool that scholars can use to assess the gender balance of their syllabi and bibliographies. The citation gap in political science is described briefly as well as why under-citing women relative to men is a problem that should be addressed by the field. The Gender Balance Assessment Tool (GBAT) is presented as a way to make assessing gender balance easier with the aim of remedying the gender gap. This is followed by an outline that explains in nontechnical terms how the tool identifies author names and then predicts their gender to produce a single document-level percentage of women authors. Finally, best practices for diversity in syllabi and bibliographies are discussed, and various public sources that can be used to find scholarly work by women, as well as scholars of color, are listed.
