A nice, non-legalese summary of the Google Books story from Read Write Web:
"Google's long-running fight to digitize the world's written works has closed two more chapters, but the story hasn't quite reached the end. Despite stakes that include millions of dollars of ad revenue for Google versus the potential loss of revenue and royalties for publishers and authors, however, the epic saga's climax is turning out to be surprisingly muted.
There are three parts to this story so far, with Google Books the protagonist (or antagonist, depending on your point of view) at the center of all of them. Following two separate court decisions this week and last, two of those parts are now concluded, leaving only one more thread of the tale to wrap up."
