A thought
The problem with reading stuff from multiple authors is that each one of them have a certain style to explain something. And when we are reading stuff from multiple sources, we might actually lose context about what we were trying to learn in the first place. So, can we put all of them as sources for a NotebookLM, such that we get to know what exactly the source talks about and then get into each of the topics in depth once we have a level 1 understanding about the entire syllabus?
