How to Find If a Book Has Been Translated

The problem nobody solves

You want to read a book in your language. Maybe it's a novel a friend recommended, a classic you've always meant to get to, or a non-fiction title that keeps appearing in conversations. The question is simple: has this book been translated into my language?

You go to Amazon. You search for the title. Amazon shows you the editions it sells — in three, maybe four languages. If your language isn't one of them, you assume the translation doesn't exist. But Amazon isn't a catalogue of everything that has been published. It's a shop. It shows you what it sells.

Goodreads doesn't answer this question either. Neither does Google — searching “[book title] + [language] + translation” gives you a mix of machine-translation tools, academic papers, and unrelated results. The information exists somewhere, scattered across multiple databases, but nobody brings it together.

For widely spoken languages, this is an inconvenience. For readers of minoritised languages — Catalan, Basque, Welsh, Icelandic, Georgian — it's a wall. The international ISBN databases have poor coverage of these languages, and the major platforms simply don't stock most of their editions.

Where the data actually lives

There is no single database that catalogues every book translation in every language. Instead, the information is spread across several sources, each with its own strengths and blind spots:

Open Library (openlibrary.org) is an open catalogue with millions of editions. It has decent coverage of books published in English, Spanish, French, and German, but is much thinner for other languages. ISBNdb is a commercial ISBN database — comprehensive for books with ISBNs, but it uses inconsistent language labels and doesn't cover works published without an ISBN. Wikidata knows which languages a canonical work has been translated into, but often lacks the specific edition details (publisher, year, ISBN). Google Books has scanned millions of volumes but its metadata is often incomplete or inaccurate.

Then there are national libraries: Japan's National Diet Library (NDL) has excellent coverage of Japanese editions, and the National Library of Israel (NLI) covers Hebrew thoroughly. But their data doesn't appear in the international databases that most people search.

The translation exists. The data exists. But it lives in six different places, and nobody is looking at all six simultaneously.

How Zenòdot searches all of them at once

Zenòdot is a free, independent tool that does exactly this. When you type a book title, it searches six databases in parallel: Open Library, Wikidata, ISBNdb, Google Books, NDL (Japan), and NLI (Israel). It cross-references the results, identifies the work, and groups every known edition by language.

The results are divided into two categories. Verified translations are editions with an ISBN that Zenòdot has matched to the work — you can buy or borrow these. Documented translations are languages where Wikidata records that a translation exists, even if Zenòdot doesn't have the specific edition yet. This distinction matters: it means Zenòdot tells you what it knows, not just what it can sell.

For example, if you search for Gabriel García Márquez's One Hundred Years of Solitude, Zenòdot will show you verified editions in dozens of languages, plus documented translations in languages where Wikidata records a translation but no ISBN is available in the international databases. A reader of Catalan, Basque, or Georgian can finally see that the book has been translated into their language — even if Amazon doesn't stock it.

Expanding coverage

Six databases is a start, not a ceiling. We are actively working to integrate additional data sources — including UNESCO's Index Translationum, which documents over 2 million translated works worldwide. We are also in contact with cultural institutions and national libraries in several countries to explore ways of improving coverage for languages that the international ISBN system underserves.

Japan and Israel were the first national libraries we managed to integrate — their APIs were accessible and well-documented. But they also showed us how much is missing: non-Latin scripts are where the coverage gaps are widest, and there are many more writing systems and catalogues to reach.

The goal is not to build yet another isolated catalogue, but to connect the ones that already exist. Every new source we integrate makes the cross-referencing more complete — and makes it more likely that a reader searching for a book in Basque, Welsh, or Georgian will find what they're looking for.

To be clear: Zenòdot is not perfect. There are translations that exist but don't appear in any of the databases we search — particularly for smaller publishers and minoritised languages, where editions are often catalogued only in local or national systems that we haven't integrated yet. If you search for a book and the translation you know exists doesn't show up, that's a gap in the data, not proof that the translation doesn't exist. We'd rather be honest about what we don't cover than pretend we cover everything.

What if the translation doesn't exist?

Sometimes it genuinely hasn't been translated. In that case, Zenòdot lets you register demand: click “I want this book in [language]” and your request is recorded. This data is anonymous and aggregated — it's not a petition, it's a signal. Over time, these signals build a picture of which books readers want in which languages. That information didn't exist anywhere before.

If you know that a translation exists but Zenòdot doesn't have it, you can contribute the ISBN directly. Every contribution is reviewed before it appears in the results.
