Learning roadmap request: compiling a "Mathematics Stack Exchange Undergraduate Bibliography"

Question

[Book recommendation] questions are quite popular on this website, which is, at least for me, one of the best places to get useful and insightful suggestions because it gathers a great number of experts in different areas of mathematics.

In my opinion, it would be very beneficial for the organization of the site (and for the many undergraduate students searching for guidance when facing a new course or looking for a good learning roadmap -- like myself) to make one thread that collects a big "Mathematics Stack Exchange Undergraduate Mathematics Bibliography" divided by categories just like the nice one proposed here, but surely more comprehensive (given the much larger number of contributors).

This thread should collect sparse material already available on the website but hard to find among the numerous questions and also new inputs. Ideally each entry should be briefly commented with matter-of-fact remarks.
