As trans people (including those on the nonbinary spectrum) start to feel safer expressing their identities in public, many libraries are making an effort to show that they welcome people of all gender identities. Yet there are a lot of potential barriers to actively supporting trans people, including lack of knowledge about their needs and lack of funding or institutional support. This book, written by trans library workers, is designed to dismantle some of these barriers and is relevant for library workers of any background/position. Introductory chapters are for people with little knowledge about trans identities, while later chapters address specific situations-such as adding all-gender restrooms, interacting respectfully with trans coworkers, deciding what information to require on library card applications, writing inclusive job postings, making collection development decisions, and more. For each topic, there are sections on easy fixes, best practices, and example language.
