A reference should contain a timestamp or a page number. That’s always been the standard for citations. You don’t just reference a book.

Also, whatever claim from the original material supports your argument should be quoted or paraphrased by you in your argument.

Citations aren’t the same as bibliography. A citation is just in case a person doesn’t trust your claim that “A said X”; they can follow your citation to check if that’s true.

Bibliography is further reading, if a person wants to know more about what you’re saying.
