About another edition of the book mentionned above, I noticed that the ISBN seems to be shared with another book from the same author.

The book on GR:

The results on Amazon:
http://www.amazon.com/s/ref=nb_sb_nos...
And on OpenISBN:
http://openisbn.com/isbn/0600387801/

Sorry, I don't have time to check it into detail now, maybe someone can do it? Thanks.

re 1, ebook edition added here:

re 2, i'm not sure how reliable openisbn is. However, WorldCat is considered the gold standard around here, and worldcat says the GR record is correct:

http://www.worldcat.org/title/tremor-...

I went ahead and added more info from both WorldCat and Amazon to that edition.
