To follow the example of The Definitive C++ Book Guide and List for C Books here is a wiki post for organization.
A tag search for "C" and "Books" returns no complete book list results as of writing this question. That search is here.
This post is to providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate quality, headings, etc.
