Resource list?

[Grotius]

Is there a screen somewhere that shows us how many of each luxury resource we're using and how many are free? I know the strategic resources are on the top bar, and I know the happiness mouseover shows me which luxuries are contributing to my happiness. But it would be nice to have an overall luxury screen showing me what I'm using, what I'm trading for, how many extras I have, etc. Is there one?

As is, I go into diplomacy, find another civ with spare luxuries, and then hope I have some extras to trade them. It'd be nice to know what I've got before I dial up evil Katherine.

how many of each luxury resource we're using

There is no concept like this of "how much". Each luxury resource gives you 5 happiness, more with some social policies. Any excess goes into your golden age bin, so more happiness is always better.

You can see which luxuries you have in mouseover text on your happiness in the top bar (left of the strategic resource).

You can see what resource trade deals you have (and thus your imports) in the diplomacy screen.

how many extras I have

You can see how many spares you have in the diplomacy window with any other leader; just open the luxury goods tab on your side, anything more than 1 is excess, you never get any direct use from second or further copies of a given luxury.

I'm not sure if this is always available elsewhere, it probably is, but there is no harm in using the diplomacy window in checking (they don't get annoyed by you talking to them).
