Hi Sylvia,

Many older maps were laid out on a zero meridian other than Greenwich, our current meridian. Often times there is a note that will say London Meridian, meridian de Paris, Ferro, etc. Seems most countries used their own capitals as their own zero meridian. 

When this happens, those lats won't match modern latitudes. You can still put modern coordinates in the record. Those can come from the OCLC authority record or from sources such as bounding box. Then add a 500 note "Ferro meridian" or something like that.

If your situation is something other than this example, I'm stumped. Perhaps share a photo of the map in question.

Hello, Great Brain!

 

I’m seeking wisdom on how to approach a particular situation.  What do you do about a map where the title says it is for a particular location, but the coordinates and everything else about the map show that it is actually for a different location?

 

I suppose I could wind up with a catalog record in which the title says the title as it is presented on the map, but then the coordinates and subject terms and everything else about the catalog record describe the map as it really is.  But that seems ornery from a user perspective, because then you are going to see that map in the catalog and click on the title, and then the rest of the description is different than that.  I suppose maybe there’s a way to do some kind of bracketed thing, to show that the map says it is one title but the map is actually for a different location.

 

Any insight is much appreciated.

 

Thanks much,

 

Sylvia
