- amelius 8y agoDoes this scale? What are the country codes for Computerland, Phoneland, Chairland, Deskland?
- mattkrause 8y agoThere is a Musicland (979) but Bookland seems to “invaded” parts of its namespace! These are hacks so that you only need one table rather than separate lists of ISBNs and EANs. Chairs (etc) didn’t have a pre-existing registry so....no need Chairland.
