From what I've read, the rediscovery of the Book of Abraham at the Met, wasn't a rediscovery at all.   
 To wit:  2012 "Book of Abraham, I presume" talk 
 As the author of that article/talk notes, members of the church don't believe the facsimiles are the Book of Abraham.  At most, we believe they are part of it or included with the Book of Abraham for interest' sake.  What this article really needs is for the facsimiles to have their own, related article, and a serious discussion of the Book of Abraham here.  Apart from that, the discussion of the facsimiles is pretty good, if a bit top heavy on the picking apart, but I'd like to see a more recent translation of the facsimiles.  We could keep the current one, too for fun.
