Yes, you do it all the time in real life when talking to people. If someone isn’t contributing to the conversation you so don’t invite them back, or change topic or leave. It’s normal human behavior.

Yeah pick your favorite university, lookup the course catalog for your subject of interest, then for each class grab the syllabus/reading list for that class.

Use your favorite online resources to get those books/papers.
