If one talked about illegal download, z library and pdf drive in the past can provide you unlimited academic books. Sadly both gone. I would not have read about quantum field theory … not that I have no access to u library. But you need to surf those books to find one you can “understand” before you dig in. Even buy one as reading read book is so much better.
