I have never seen the book but if 30 something pages is that thing amazon wants $175 for or somewhere else they ask $85 to $120, it seems to me that it is NOT the real or the fully complete article. Why is that book so expensive anyway, I have refference books for other engineering fields that are very big and not so much money, seems odd to me unless it is a rarity or antiquated.
No, you are correct this is most certainly not THE TEXT and I should have been more clear than simply calling them 'comment files' by chapter. They are nowhere near the detail or content of the original text, but depending on the persons needs may or may not be of some help.
No worries. Care should be taken regarding valuing of books on this site. There are, as anywhere, less than scrupulous dealers. This is true primarily of older and rarer books, but care all the same.
I spend more time there than most and have come to know it well. Glad it serves you well.
