It appears that this was just an announcement, probably just a press release. The major papers (NY Times,
Washington Post, Chicago Tribune, Wall Street Journal, LA Times--thank goodness for the ProQuest historic
newspaper databases) all covered the story with the same information, much of which sounds like PR talk (an 8

seeing the records.
Ads start showing up in July, which is about the time the first reviews appear.
