The book link on the IU course website is very outdated

After working through the first 10 or so lectures I started wondering why the book didn't seem to match the content. Turns out the version linked from the course is half the page count and structured a little differently than the latest version!

The link in question: https://iu.instructure.com/courses/1735985/files

I'm loving/devouring this course, btw!
