There is a new and much better way to read the course book on line! ElevenLearning is a startup company in Cambridge, MA, that is creating a new model for textbook publishing that is open-source, collaborative, and does not extort the extravagant charges from students that keep traditional textbook publishers obscenely profitable.
To read the book:
You will be able to read the book much more easily on-line using their system than you can using the PDFs. It should also work well on other devices such as iPads and Android tablets. You can also add notes to yourself, and even share notes with other people reading the book. I still encourage you to do most of your reading using a printed copy of the book, but to take advantage of the on-line system for quick access as well as recording and sharing notes.
This is a new system underdevelopment, so the ElevenLearning developers and I will be happy to hear any comments you have about the system.
