Research Design, Second Edition: Quantitative, Qualitative, Mixed Methods, Arts-Based, and Community-Based Participatory Research Approaches

I am now half way through my research methods class using this book only to find that the pages are off significantly. My copy us missing half of chapter 6 and two thirds of chapter 7. And has a large portion of chapter5 five inserted in that spot. I have no idea how to go about getting this information outside of just ordering an new copy of the book and hoping for the best. Very disappointing.
