As is always the case with Laboratorium posts, Professor James Grimmelmann (New York Law School) does an outstanding job providing links to all primary documents along with his expert analysis.
From his Latest Blog Post:
On Friday, the parties filed their motions for summary judgment in the HathiTrust case, along with thousands of pages of supporting documents.
[I’ll] summarize the arguments in the briefs themselves, to give readers a sense of how the case is developing. There are three briefs in: the Authors Guild (and other authors and groups) on the plaintiff side, and HathiTrust and the National Federation of the Blind (and individual blind students) on the defendant side. Interestingly, the three briefs take on slightly different issues. Today, I’ll discuss the prima facie case of infringement and Section 108; fair use will follow later in the week.
