- Couldn't agree more, as a starting grad. student, I'm more than overwhelmed
- by the number of articles it would have been nice to have read. But, I
- guess it's an indication of the rapid development of the area...
- (I read Kashlinskys article because it by chance dealt with the same

- luckily it came before I had started !)

- Well, I should say that he is not using unbiased CDM. He assumes a bias
- parameter of about 2 in the discussion, and calculates results for b=1 and 2.
