I prefer articles more than books tbh! Just because articles can be more timely and up-to-date with the latest of Bitcoin. The whole ecosystem is constantly changing, so most of my study isn't reading a bunch of books, but keeping up with the latest progression and thoughts in threads/articles.

Here's a list of one book (The Blocksize War) and a few articles I found useful for shaping my thoughts for creating The Great Resistance:

The Blocksize War by Jonathan Bier - the entire book is free online, just change the link to chapter-2 to access chapter 2, etc.
