What exactly "Nearby" means

[Vexus]

Posted this in general, but then realized it would be more appropriate here and I was surprised at the minimal response:

" This is a difficult topic to use the search function with, so my apologies if this has been covered multiple times, but . . .

Can I presume that "nearby" when referring to a building's requirement for a resource means within the BFH? If so, placing Iron, Horses, Elephants, Sea Resources, Wine and Incense in reach of at least 2 if not 3 city's BFH would be a basic pillar of strategic city placement, correct?

Somebody said they thought nearby meant being worked, and I originally thought so too, but then the wording of the requirements for the mint made me think otherwise:

"Each source of city’s worked Gold and Silver provides an extra +3
Gold."

If "nearby" means worked within a city's BFH. Then does anyone know if horses is within 2 BFH's and you switch the worked resource from one city to the other (allowing you to build a circus in each), would the happiness effect of the circus only remain valid so long as the resource was worked by that city? . . .

Well it could mean something like in the BFH and alloted to the city. Like in civ4 some tiles would be grayed out on the city screen since they 'belonged' to a different city.

I suspect it means within the 3 tile radius (equivalent of BFC) and assigned to the city, that's the best suggestion I've heard from anyone so far.

If it's outside 3 tiles/not in your culture, doesn't count.

If it overlaps between two cities, it goes to whichever city it is assigned to in the city screen.

my guess is if its within the radius of two cities, both cities get the benefit irrespective of whom the tile is assigned to.

My guess is that this is not the case, and that Earthling is correct.
One resource gives a bonus once.
Otherwise its east to exploit by say placing 4 cities so that they all happen to just overlap a particular bonus tile.
