My point wasn't that google caches it. My point was that the link is to a copyrighted work of Larry Wall et al, via O'Rielly (who quite likely actualy owns the copyright, but I'm too tired and drunk to check), which they have expressedly not given permission to distribte. My complaint isn't at Google, who is just doing their level best to provide relevant search results and related services (which they do very well), but at the people who put a copy of Programing Perl on a publicly-accessable web-site, in voilation of it's copyright. (I suspect the people in question bought a site license for the CD bookshelf or O'Rielly Safari, but I'm quite certianly not at their site.)
