I'm currently working with a collection of 60 plus ego net 
diagrams created with UCINET.

I'm trying to group them .. to form some crude typology based 
on, essentially, their ratio of structural holes.  Simple star 
nets are obvious as are those with every alter in at least one 
dyad or triad.  Some have small or large clusters of connected 
alters.  And most have combinations of "singletons" (what Burt 
calls center-periphery), dyads, triads and clusters..

A search for papers describing a tentative typology has been 

Could anyone point me to papers my search has missed?
