Now the reason for the two-point deduction for the TB issue:
I was wondering how you want to get this heavy "ham" hardcover in a pocket, in which the only glued back somehow has to hold everything together. I tapped on a two-volume edition (which incidentally is the original and should have done quietly, because the hardback is extremely difficult).
Instead, you gave up about 2/3 of the images and also replaced some of the high-quality photos by simpler illustrations on a white background, such as one often sees in textbooks.
The lyrics are still wonderful, but I would rather recommend to anyone the Hardcover with all pictures.
