cannonical URLs in <link> tag

Having observed a few canonical URL solutions in Digital Library world, such as Handle, PURL, DOI, it is really nice to see the cannonical URLs from Google. Google partially solves the problem by simply adding a <link rel="canonical" href=""> to specify your preferred version.

It always surprises me how elegant and simple a solution can be, and how long it takes to find these simple solutions.
