Foucault and Derrida Round 3

Derrida makes critical references to geneaology in _Politics of Friendship_
(he does in an interview specify it to Nietzschean genealogy, however it
seems that the criticism would still apply)--- In that same interview he
says that in the past he had closely aligned deconstruction with genealogy.
Does anyone know of any specific references he makes to genealogy other than
within the pages of Politics of Friendship and _Resistances to
Psychoanalysis_ ??

Thanks

Oh, also, it seems that Derrida has a new book coming out _Of Hospitality_..
I also caught wind of some book entitled _the politics of mourning_...
anyone got any info on the latter?

thanks
