Bryan,
A while back I suggested to Clark they he include reader reviews. He took it one step further and offered reviewers $5.00 credit for each one. The reviews are a bit short but they are better than nothing, as you won't see most of these things reviewed anywhere else. I don't know if it interests you, just thought I'd mention it as I am sure many would benefit from your assessments.
There are so many research and reference works in his catalog that I have no idea of the quality of and I certainly appreciate your thoughtful comments on the worth of the books you've been talking about here lately.
