That being said, as mentioned by others, there are strange kerning and line thickness issues that are not present in the source PDF.
I've created two comparison shots. On the left is the source PDf found here. On the right is the same page scanned from my book.
In the first comparison, the image quality of the right image is a function of my scanner, not the book. The point of that comparison is to show the kerning issues in the textbox that are not in the source PDF.
In the second comparison you can see the kerning in the chapter title, and the strange variation in line thickness.
HOWEVER, I'm delighted to own this book and my immense thanks to the original authors and the person who took the trouble to make it printable via Amazon!!!
