Use <link rel="canonical" ...> to prioritize newer book versions in Web search results. #184

Daniel Shahaf forwarded along the neat suggestion to embed <link 
rel="canonical" ...> tags in the book's HTML pages in order to prioritize newer 
book versions in Web search results.

Something to consider doing for the 1.6-and-earlier versions of the book?

In my response, I thought it would be valuable even for the youngest version of 
the book so that forks thereof that spring up around the Web would point to the 
canonical location.  I may have been too hasty, though, as I *think* I just 
read that this tag only works (as in, is recognized and handled as expected) 
when the source and canonical target are on the same server.
