looking for a book about transgender, how the topic is handled in different countrys and the journey trans people go through

Hello, in the last months I habe taken an interest in the journey trans people go trough to be officially recognized as the gender they are and the surgical operations many go through to adapt their body to their Gender, how it differs in different states, and what can be done to improve this. Unfortunately (as you have probably read in the last sentence) I have no idea about anything regarding this topic. Therefore, I am asking if you know any worthwhile books, websites or any other resources where I can inform myself about these topics, preferably they should be in English or German, but I can just as well use a translator if it is any other language. Thank you for your answers in advance!
