Is there any explanation by the best writers how to read books?

I can't find any sources how THE WRITERS (which are considered the best one. Like the classics writers, for example) explain how THEY ANALYZE books.

If you can cite me some authors. Then could you (it's just bid) broadly explain their strategy of analyzing?

What do think about his position of understading how to read? (There is English subtitle)
