Hathi Trust: better than Google?

Aren't descendants great? My son reads blogs I don't know about and discovers an alternative to Google Book Search that offers more full-text digital book images than Google does: Hathi Trust, which resides in Mirlyn, the University of Michigan's online catalog. I found that Google offers only snippet views of The Older Middle West by Henry Clyde Hubbart, whereas at Hathi Trust I could (but didn't) read the whole thing.

Apparently you can also sign up and create public collections of Hathi Trust books. No one has done "genealogy" yet, but there are hundreds of old genealogies digitized here. Caveat lector -- check out those unsourced puppies, please.
