This page gives the census of membership in cometary families. There are eight lists:
You can send me comments, they are very much appreciated.
For fun, check out my other lists: list of SIRTF solar system observations, list of low-Tisserand asteroids.
This list was last updated on November 21th, 2009. Current project is to add in citations for all the elements.
Halley-Family, traditionally defined.
