Every once in a while, we get a question asking for a book or other educational reference on a particular topic at a particular level. This is a meta-question that collects all those links together. If you're looking for book recommendations, this is probably the place to start.
If you have a question to add, please edit it in. However, make sure of a few things first:
- The question should be tagged resource-recommendations
- It should be of the form "What are good books to learn/study [subject] at [level]?"
- It shouldn't duplicate a topic and level that's already on the list
