There is a really interesting book review of both Henry Hubert's and Roger
Graves' work in the most recent edition of the JAC.
I recommend the review not only because it praises both Henry and Roger but
also because the reviewer, an American, discovers that it is really, really
different up here. And she's very surprised ( and possibly a little hurt
because some of the difference is a kind of anti-Americanism).
The article is a good read.
