I have read 4-5 books on this topic -- this is by far the best. The others are too lengthy, more for academia or career-services professionals. But this one carries the nuts & bolts, along with the clear step-by-step methods & best advice that the other books gloss over or ignore.
With this book, I have coached several colleagues & myself -- one of them got a salary offer $10,000 ABOVE what the company was initially offering. Another negotiated a sign-on bonus that was originally non-existent. When I first read it (in '99), I gave my closest friends copies of it for Christmas! How's that for an endorsement?
