Walt Crawford has published "It Was Never a Universal Library: Three Years of the Google Book Settlement" in Cites & Insights: Crawford at Large.
Here's an excerpt:
Remember the Google Books settlement? It was going to settle a four-year-old pair of lawsuits (four years old then, eight years old now) against Google (by the Association of American Publishers, AAP, and the Authors Guild, AG) asserting that Google was infringing on copyright through its two-line snippets from in-copyright books scanned in the Google Library Project—and by the scanning itself. Later, a third group representing media photographers also sued Google for the same actions. . . .
This is a long set of notes and comments (cites & insights). It strikes me that the topic and complexity deserve that length—but note that I'm offering much briefer excerpts and comments on most items than I normally would in this sort of roundup.
After two sets of general notes and overviews (one before the settlement was rejected, one after) I'm breaking the discussion down by topics rather than chronologically.
