EDItEUR has launched a multilingual online resource for the ONIX codelists, at, which will become a hub for codelist translations. Initial languages include English, Italian, Spanish and Norwegian, with others to be added over the next few months.

ONIX national groups have an important role here, as they can coordinate translations and if necessary resolve any translation issues that arise. The browser also gives each code in the codelists a unique URL (at least in a particular language), and use will be made of this in the future. For example, the URL for ISBN, code 15 in list 5, is
