C.E. Petit has published "Suing HathiTrust" in Scrivener's Error: Warped Weft.
Here's an excerpt:
This is an initial review only of the third segment of the Google BookScan lawsuits, generally known as the "HathiTrust suit" and formally known as Authors' Guild, Inc. v. HathiTrust, No. 11-6351 (S.D.N.Y.) (Baer, J.). The first two segments were the Authors' Guild's lawsuit against Google, and the publishers' lawsuit against Google (which were later consolidated… and at this writing may be severing). As a side note, the HathiTrust matter was referred to Judge Chin for further consolidation with the existing GBS suits, but was rejected as not sufficiently related… and inconsistent with Judge Chin's elevation to the Second Circuit, although the rejection did not emphasize that issue.
