This is a coil-bound print copy of the readings that are available to you absolutely FREE on Canvas (go to the course, click on "files," then "course documents" - it's there as an Adobe .PDF). But, if you like to have a tangible copy of the readings to highlight, underline, take notes in, bookmark, etc. (like I do), then this is perfect for you, and won't burn though your printer cartridge. Your purchase of this book is ABSOLUTELY NOT REQUIRED, but it has been provided for you as an option for your convenience. Please note - this is the COMPACT (6" by 9" size) that does not correspond page for page with the PDFs posted in Canvas.
