Luxury resource question

[steve308]

Say I have a civilization that controls 3 of the same luxury resource, say Ivory or Silks. I notice in my city screen that these resources are making my people happy. My question is: Do I get 3 times as many happy people from all the extra resources? Or am I better off trading the extra 2 resources? I can't seem to find this explained anywhere in the manual or the FAQ.

Thanks for any info,

You only get the benefit of one fo them. Trade the others.
