While all-encompassing and comprehensive, it's not an accessible book. Harley doesn't write for the average Joe, and he can even be anti-Chomskian without wanting to (or maybe he does). The bold-letter definitions that accompany the text are quite useful, as are some of the tables and graphs. Other than that, I find some of the photos completely unnecessary (e.g., photo of a child with caption reading, "child." How useful! I thought children were a myth!) Overall, a book that induces headaches, despite the amount of information it contains and its good organization. I'm personally not a fan of books that have are written in columns as though they were newspapers - it is actually more tiring to read than it is fluent. I'm sure there are better textbooks out there, and I sure hope Trevor and I won't have to meet again too soon.
