Dr. Joanne Freeman's course from Yale is a great starting point. You can download all of the lectures to listen to on a local device and don't need to worry about being connected to the internet. Freeman is easy to follow, clear, and thoughtful about how she presents information. You can skim the supporting materials to review the primary sources she cites. Happy listening!
