Lisa Levy has a good review of it here: A Peaceful, But Very Interesting Pursuit – The Rumpus.net.
It seems like something that Eliot liked, not only for what it provided him, but for what he was doing. And while Ezra Pound and others worried about how it affected his writing, I believe Eliot did well with this job: it may have even helped him instead of harmed him when it came to writing.
