VERY PUZZLING. At Wrox.com, this book is advertized as of 1000 pages and 
25 chapters and has a cover with over 10 pictures of authors. On the other 
hand, at Amazon.com it is advertized as of 1400 pages and 26 chapters and 
has only 4 pictures of authors on its cover.

Is it the same book?
It seems to be a good book but I don't know which information is more 
accurate? thanks. :-)
