This pdf file seems created from this site. I check the information of the pdf file by pdfinfo the pdf file:Creator:        pdftk 1.12 - www.pdftk.comProducer:       itext-paulo (lowagie.com)[JDK1.1] - build 132CreationDate:   Mon Mar 20 14:07:22 2006ModDate:        Mon Mar 20 14:07:22 2006Tagged:         noForm:           nonePages:          565Encrypted:      noPage size:      612 x 792 pts (letter)Page rot:       0File size:      6657623 bytesOptimized:      noPDF version:    1.5I don't know pdftk can create pdf files from webpages. I guess it was created by some other way (which can add number to left bottom of each page), and then processed by pdftk. But I am happy to be wrong. I like to know how that can be created (so long ago), because I would like to have a pdf file from the newer version of the book. 
How can this pdf file be created from this website?
