They are a couple of fascinating documents. The Authors Guild seems gobsmacked by the final ruling, and so am I. Perhaps the SCOTUS was correct to turn down hearing the case, if only to let the issue settle a little more, but it really feels like it's likely to be overturned in the near future.
There are some interesting tidbits in the opinions: 1) In the definitive ruling, the judge decides that the harm done to the market for the books is negligible, or overcome by the transformative "purpose" of the the usage ("purpose" is significant because most examples of fair use include some type of new creative "expression"). This is surprising to me. 2) Google Books is ruled fair use in part because the book descriptions (and snippets?) are metadata describing the books, information that should not be controlled by the authors.
