hittite nouns

I would be grateful to know a site on the web where I can find
paradigms for Hittite nouns.
In Szemerényi's Einführung ... from 1980 there the conjugation of hi-
and mi-verbs are given and discussed, but nothing about declension.
It seems that declension is of no interest for comparative IE
research.
I would also be grateful if somebody could explain why Hittite
declension is uninteresting and irrelevant.
