General Relativity and Cosmology Textbook Recommendations

Finding a good textbook to learn about Einstein's theory of general relativity as well as modern developments in cosmology is not always an easy task. This video goes through some of the resources I've personally found quite helpful as well as those commonly recommended by other more experienced practitioners of physics. I hope to have provided you with some good recommendations on any educational level (bachelor, master, and beyond) such that you could further supplement your learning.
