I kept this book for the longest time while I was working on my dissertation (as adjunct faculty I could keep for semester and renew for semesters as long as noone else requested it. Strangely, nobody did.) It is an excellent collection of articles, essays, etc for a researcher. It covers a large scope of topics and the articles are solidly written by excellent researchers.I don't know why professors didn't choose this as a research textbook. Perhaps the scope of the book is intimidating for a professor or maybe too ambitious to cover within any semester or academic year. With nearly 1000 pages, it is also an extremely heavy and thick book to carry around.
