Read during the #TransRightsReadathon. A good overview, updated in 2017, of trans history from the 1950s on. It focuses on human rights and social justice in historical social context, but does include some scientific/medical history as well. The glossary at the beginning is useful, but be advised, as the author points out, that language can change rapidly, so it should be a starting point and guide to understanding the terminology used in the book rather than a definitive source for current usage.
