# Getgbook ## TOS Google's terms of service forbid using anything but a browser to access their sites. This is absurd and ruinous. See section 5.3 of http://www.google.com/accounts/TOS. Thankfully, however, for Google Books one is only bound to it "for digital content you purchase through the Google Books service," which does not affect this program. See http://www.google.com/googlebooks/tos.html ## robots.txt Their robots.txt allows certain book pages, but disallows others. We use two types of URL: http://books.google.com/books?id=&pg=&jscmd=click3 http://books.google.com/books?id=&pg=&img=1&zoom=3&hl=en& robots.txt disallows /books?*jscmd=* and /books?*pg=*. However, Google consider Allow statements to overrule disallow statements if they are longer. And they happen to allow /books?*q=subject:*. So, we append that to both url types (it has no effect on them), and we are obeying robots.txt
