What should I be reading? In what order?

You should be reading my lecture notes (click HANDOUTS at the ILT site) and corresponding textbook sections.

As long as you thoroughly understand concepts described in my lecture notes, it does not matter which one you read first.

My lecture will follow the textbook, from Chapter 1 through Chapter 13 and maybe a bit of Chapter 14, if we have time. The order of my lecture will be almost identical with the order of book chapters, and so keep reading, as much as you are able.
