I was excited when I first scanned through a friends copy of this book because of its treatment of modern compiler design issues. I ran out, ordered the book, read through it more carefully and realized that it was nothing more than a collection of papers. There would be nothing wrong with this if it were so advertised. The book lacks original analysis. I wouldn't stedfastly say DON'T by this, but, I would say you might be better off just going to your local college CS library and grabbing all the relevant papers referened in the book.
