Add Algorithms by Robert Sedgewick on the basis that it's a freely available book from a reputable institution (it's the textbook for the Princeton Coursera courses). That being said, I haven't had the chance of reading the book so I can't personally comment on its quality.
* Updated the links for books that have a newer edition. I have included the authors' home page for the book where possible.
* Updated some titles to reflect the linked edition. I have maintained the original format (``2e`` for the books in the ``Programming`` section ``(2nd Edition)`` for the books in the other sections). Unifying the format could be something to consider.
Removed Sheldon Axler's "Linear Algebra Done Right (FREE)" because it is no longer free after the end of July 2020. It was made free temporarily due to COVID-19.
This books contains easy to understand introduction to the automata theory, which is missing in "Introduction to computing" book by David Evans. It does not require complicated math, so it can be useful to students who do not want to become theoretical computer scientists, but want do have general understanding of it's topics. Also, it almost perfectly matches The Automata Theory course we have in the curriculum.
This is probably the best introduction to computer systems for programmers. It contains all needed essentials of computer architecture, describes how C language works internally (e.g. how data structures are organized in memory and managed on machine language level) and even describes essentials of operating systems.
PBRT is an amazing book detailing the implementation of a real, well-developed path tracer and is used in many real Computer Graphics courses. The authors have no released it for free, so it would make a great addition to the curriculum.
