This is a standard book that anyone in the social sciences should read. It's a classic. I am very disappointed, however, with the quality of the physical book: the cover is very thin and the pages are on newsprint. I'll bet that after a few years it will deteriorate so that it crumbles. It will probably discolor if left in the sun. For $35 and for such an important book, this is really a shame. The 4th ed. I got from a library is well used but in great condition. This one wouldn't be the same if given the same use. I would like to recommend buying the previous edition but this one seems to bring in quite a few newer examples and recent experimental support for the theories. Caveat emptor.
