Rulebook, Codexes, what else?

[narrativium]

Other than the core rulebook and the single-army codexes, could someone list the rulebooks available for 40K at the moment?

My list so far:
Apocalypse, Apocalypse Reloaded
Cities of Death, Cityfight (what's the difference between these two?)

Any others?

Cities of Death, Cityfight (what's the difference between these two?)

Cityfight was 3rd edition, Cities of Death is 4th.

I suppose your list could include all the various Imperial Armour books? I.e. IA 1-6, the updates, and IA: Apoc.

[Radium]

Cities of death is cityfight v2.0. Cityfight is no longer really valid.

But you also have a whole bunch of Imperial Armour books form forge world.

Edit:
Once again: ninja'd!

IA Update 2006 was officially superceded by IA:Apoc. IA Apoc isn't solely for Apocalypse now (any non-Formation data sheets provide the FOC slot)

[Culven]

The Apocalypse Datasheets from the GW site could be considered as well.

Is the Wargear book still available and valid?

OOP and no.
