Hi Chris, thanks.
The bounding boxes are stored in the "Map" description templates of the
individual images on Commons.
So for example, go to
and then scroll down.
They're not on Wikidata, because individual book illustrations are not
notable for Wikidata (at least I don't think so).
They're not on OSM, because they relate to the particular map, rather
than the feature that's being mapped. So eg different maps of the same
town or county may have different bounding boxes, depending on how much
of the surroundings are included -- and they may not exactly correspond
to any feature at all, eg where multiple map sheets are used to cover a
town or a county.
What at the moment is possible is for individual /points/ on a map
description page to be picked up, and shown on a map for the whole
category -- see eg the link at the top right of
So if /points/ can be emitted from description pages and caught by such
a template, my question is whether this could be tweaked to allow /box/
coordinates to be emitted and caught in the same way, and then shown on
a map by such a template.
I've haven't yet delved into the details of how the mechanism to catch
and then display /points/ works; but I was hoping there might be people
on this list who might know all about it, who could then advise.

I was trying to think if there was a way to do this with the
interactive Wikimedia maps. You'd need some way to extract the
bounding boxes. If they are stored in OSM or Wikidata it looks like
that might be possible programmatically with the current software. 
Otherwise it looks like a more manual process. :/
I'm afraid I'm not super savvy in this area, but maybe some of this
might be helpful?
