One of the worst textbooks I've ever had assigned to me. While the information within was useful and very relevant, the author needs to understand that the footnotes are meant for citing sources, not for writing entire paragraphs in. Furthermore, the organization of the text leaves much to be desired, I often had greater success just flipping to the index to look up the topic I was studying instead of turning to the chapter/location where (I thought) the subject logically should fall. The examples were not at all clear either, and I relied primarily on my professor's lesson notes to clarify how to actually complete calculations-based assignments. I would not recommend this textbook to others unless you absolutely need it for a class, as I did.
