The Nonbinary Encyclopedia is a comprehensive reference work of nonbinary and gender-diverse history and culture around the world and throughout time. Drawing from scholarship and the authors' lived experience, it offers readers nuanced and accessible insights into how gender has been embodied, expressed, and regulated across societies and time periods. Written by a team of academic and nonbinary authors, the encyclopedia brings together historical figures, contemporary movements, medical advancements, theoretical frameworks, and global traditions that do not fit into a binary model of gender.

The Introduction covers philosophical and conceptual topics and provides an overview. The body of the Encyclopedia features over 100 entries with a global range: nonbinary identities in cultures around the world today, medical issues, terminology, legal and political subjects, nonbinary people and traditions in history, and more. References at the end of each entry point the reader to further materials. Written in an accessible manner, this work provides an ideal entry for those wanting to know more about this important subject.
