This quarter (Spring 2013) you also have the option of purchasing an e-book from McGraw-Hill which has just the chapters with assigned reading: Chapters 1,2, 4, 6, 7, 8 and 3 (in that order) from the second edition of the text. Some of these chapters have only a few sections which will be assigned; it was not possible to select content by sections. The cover may still say Winter 2013. That's okay. We will use the same text for both Winter 2013 and Spring 2013.
When I checked, the price was $46.69. Please make sure that this option will work for you before purchasing; there are system requirements.
