Keahi Adolpho and Stephen G. Krueger write: “This comprehensive review illuminates the current state of scholarly literature on trans and gender diverse inclusion in libraries, with the intention to provide a foundation and identify gaps for further research. We found that, with the exception of works on archives and cataloging, little scholarly literature goes beyond introductory talking points on basic information about trans and gender diverse people. We conclude with a call for much more in-depth research on this essential topic.”
