[open-bibliography] Place of Publication data from the BL dataset

[Karen Coyle]

Ben, Edward Betts did some interesting work on disambiguating (or not,  
as is often the case) publishers using the ISBN prefixes. Obviously,  
it only helps when you have an ISBN... he also did some stats on  
country of publication. You can find various links here:

The one relating ISBN codes and publisher names is:

I find these kinds of studies absolutely fascinating, in part because  
they point out how ambiguous our library data really is, often because  
it's a funny world, publishing is.
