Here is a list of books that I found indispensable while learning more about bitcoin. Not all of them are about bitcoin, and a few were written before bitcoin came into existence, but all are fundamental to understanding and appreciating this extraordinary piece of code. I will eventually include my thoughts and comments about each, and welcome input to make the list more useful. This post is going to be constantly revised, and for now the order of listing should not be taken to imply a ranking.
