Dear T V Gopal,
If the seminal work is referenced, it will appear in the analysis. The
authors provide references outside their domain, don't they?
But I agree that the focus has shifted to the dynamics of citations more

direction for further research.
My apologies for the delay in answering; something went wrong in my
