I can’t link to it because I’m on mobile, but on the sidebar there’s a link to the AskHistorians book recommendation page. It’s broken down by subject/topic, and the books listed have descriptions that make it pretty easy to get the general gist of the book, as well as brief highlights or criticisms, making it pretty helpful when it comes to choosing the right book(s) for the type of reading you’re looking to do. Hope that helps!
