As is very clear from recent court cases and other events highlighted in the news, the law in the area of gender identity and sexual orientation is still in a state of flux. However, to get a grounding in the law as it currently stands, and to get more information on how to update your research in the future, it may be best to start your research with a secondary source, like a legal treatise or law review article. The Law Library of Congress has several helpful resources in its collection which are included below.
