This "book" in the LibreText tool was designed as a complete course delivery tool. The material within includes course supporting materials, such as PowerPoint slides, Test Question Libraries and Assignments. In addition it includes links to original content created for this course in the form of videos (links to YouTube) as well as external content on a wide variety of topics where great material existed.
Please note that this book is intended to be used by the instructor, and not for general access to all the students in its entirety. The instructor can certainly take as much content as needed from this book and make it available to her or his students, however, I would recommend removing access to the question banks.
