I was just reading this and was gonna recommend it to a friend! Saw the announcement from Lucia moving to a resource-based repo and digging deeper saw The Copenhagen Book, which IMHO is the best resource Auth-related I've seen in my 10+ years of career, all very well put together. Two tradeoffs I see is that it is a bit abstract, and also a bit brief/succinct in some places where it just says it as it is and not the why. But neither of those are really negatives on my book, just concessions you have to make when doing a project like this. You can dig deeper in any topic, and nowadays libraries have pretty good practical setups, so as a place where it is all bound together as a single learning resource is AMAZING. I'm even thinking of editing it and printing it!
