GoKawiilFinding a work in translation is harder than you think. Discussing the creation of Zenòdot, a cross-referencing project for books in translation, Ausiàs Tsel outlines the challenges of creating a record of translated works across different catalogues and what is lost when these records do not exist.
Le Petit Prince is one of the most translated books ever published. It exists in well over a hundred languages. But if you tried to find all those translations in a single database, you would fail. The world’s largest commercial ISBN aggregator documents editions in roughly seventy languages. The rest are scattered across national library catalogues in Tokyo, Jerusalem and Oslo, across collaborative databases like Wikidata, and across historical archives that stopped being updated fifteen years ago.
No single source covers more than two-thirds of the picture. This is not a peculiarity of one famous children’s book. It is the normal state of affairs for translated literature worldwide.
Translation discovery is not a content problem. The translations exist. It is an infrastructure problem: the metadata that should connect them is fragmented, incomplete, and unevenly distributed across institutions that were never designed to talk to each other.
A fragmented landscape
There is no global catalogue of translations. The closest attempt was UNESCO’s Index Translationum, launched in 1932 and computerised in 1979. It accumulated over two million entries across some 800 languages. But contributions from national libraries slowed, and the database has not been meaningfully updated since the late 2000s. The longest-running international bibliography of translations is, in practice, a historical archive.
What remains is a patchwork. National libraries document what is published within their borders, not what is translated from their literatures into other languages. Commercial aggregators like ISBNdb hold vast numbers of records but with language metadata that is often missing, incorrect, or ambiguous. Wikidata contains translation data contributed by volunteers, but with significant gaps and biases toward well-resourced languages. Nine national library catalogues, from Norway to Taiwan, together contribute less than ten per cent of the editions tracked by Zenòdot, an independent cross-referencing project, while commercial aggregators contribute the largest share but still fall short of majority coverage (full disclosure: I am its creator). Each source holds pieces that no other source has. Nearly ninety per cent of the ISBN-verified editions in the system appear in only one of its twenty-three sources.
Every database holds something unique. None holds everything.
Visibility and bibliodiversity
If a translation is not in a database, it is functionally invisible. For smaller languages, this is not a technical inconvenience. It is a form of cultural erasure.
