It’s what is commonly printed on the book. Besides the title and the author(s), the title page often has three other things: Publisher name, city, year.
For example the first edition of Farmer Giles of Ham states:
London MCMXLIX
George Allen and Unwin Ltd
I’m surprised that “as on release” is suddenly a strange concept. ![]()
I only know that the standard is really old. It already exists in the 1876 rules by Charles A. Cutter, and is probably even older than that.
Back in the days editions and publishers were in general smaller and a lot more local than they are now; especially smaller publishers didn’t distribute their books to the whole country (some of them still don’t). So the intended “market” could have been just the town.
The editions originating from different cities can have differences, including differences in printing and paper quality, binding, and contents. As you can imagine, this meant that the location used to be quite important when it came down to differentiating editions.
That said, I’m not sure how important the location is now, considering other identifiers exist, but the practice to catalog it still seems to persist. And we are not limiting the contents of the site to just modern books by big publishers, right?
While I’d prefer not to reinvent the wheel, I wouldn’t be opposed to having an additional field or two. I’d even add Printing Location to the list.
Tbh, Discogs could use more than the Country field too (“Manufactured in”, etc.), to cover locations that are actually printed on the releases.
