Yes, but I was rather inquiring about whether it was even possible to do so. That list is huge and most likely growing. One of the companies on the list is McGraw-Hill Education. I have to use their products at my school - how do I get around that?
I love how you can pick nearly any topic in almost any subject(especially computer science) and find an amazing book for free, or for about $60, yet every textbook my school uses gets < 2 stars on amazon and costs $150.
My "favorite" was a biology book written by a guy with a B.S. in journalism. He published the book years ago and every year he releases a new edition with the chapters out of order.
Be a proud pirate.
