Just got my copy from amazon.ca ("Ships from and sold by Amazon.ca.") I'm worried this is a counterfeit. Can anyone who ordered theirs from CUP, or amazon.com help confirm? I'm seeing:
I didn't order the X-chapters yet, but have just received a new copy of the main 3rd edition volume. (The "improved" version, whch Amazon.co.uk currently sells at a low price, as discussed in another thread here. I wanted a copy with the known errors corrected.)
Compared to my 1st printing of the 3rd edition, I can confirm that the paper of the new printing is indeed thinner. The book is a few mm thinner than the original printing, and more noticeably the printing on the reverse side is indeed much more visible with the new paper.
The top margin is smaller than the bottom one; that's probably intentional. (It's 1.4 cm, not mm, right?). But no skewed printing that I would have noticed.
So I guess the new choice of paper is a general CUP decision. Not an improvement. The new book is certainly usable, but the original printing is more pleasant to read. I am torn which of the two copies I should make my main go-to book now...
