There is a book on which much of this course is based. The book is not required for this course, since the instructional component of this class is the many videos which provide the course content. However, the book is available for free in PDF format. You are welcome to access the book online or to download it for your own use.
The topic in Section 1.5 is not included in the text. And the topic in Section 3.3 of the text is not now included in the class. Other than those two minor differences, the content of the book closely matches the content of the present day class.
This book is made available to you via the link below as an optional resource for students who might appreciate additional background material and examples on the topics of this class.
