Translating LaTeX Bibliography References

If you have a LaTeX project with a reference list, you have probably found that translating it is not the same as translating the body text. A bibliography is made of citation keys, author names, DOIs, venue names and titles, and some of those must stay exactly as they are or your citations will break. Researchers, students and authors who need a translated version of a paper often run into this when they try to translate the whole source at once.

This guide is for anyone who needs a translated LaTeX bibliography, whether for a bilingual submission, a review copy or a thesis chapter. You will get a clear rule for which reference fields to keep, a step-by-step way to run the translation with OmniDoc, and a checklist for confirming the result still compiles and cites correctly.

How should you handle LaTeX bibliography translation? The short answer

Translate the explanatory text around the references and keep the identifying parts of each entry in their original form. Then compile the result and confirm that every citation still resolves.

Your situation	What to do	Why
You need a bilingual reference list	Keep the original entry and add the translated title in brackets or a separate note	Readers can still find the cited work by its original title
You only need a translated version for reading	Translate the surrounding text and keep titles, DOIs and keys unchanged	The document reads well and the citations still match their sources
The cited works are in another language	Keep the original title and venue, and check the author name spelling	Original titles are how readers and databases look up the work
Your project uses a reference manager export	Keep the citation keys exactly as they were	Keys are how the body text points to each entry
You will submit the file to a journal	Follow the journal's rules on bilingual or translated references	Some venues have their own requirements for reference formatting

Before you start

Five checks before you upload anything will save you from a broken project later.

Confirm the original compiles. If the project already fails to build, a translation will not fix it, and you will not know whether a new error came from the translation. Compile it once and keep the PDF as your reference point.
Back up the source package. Keep an untouched copy of the whole project folder, including the bibliography file and any custom style files. You need it for comparison and as a fallback.
List the citation keys. Keys look like smith2021method and appear inside \cite commands in the body. Write down a few of them so you can search for them in the output.
Decide which entries are special. Entries for non-English sources, datasets, software, or works with official translated titles need a clear rule. Settle this before translating so you can check the result against it.
Confirm your target language and purpose. A bilingual reference list and a translation-only reference list call for different checks, so know which one you need before you choose the output option.

Translating the whole LaTeX project in OmniDoc, step by step

OmniDoc translates LaTeX source packages on omnidoc.top, so you can run the whole project through the same process. The steps below are a general workflow built around that. Adjust them to your project's structure.

Package the project. Put the main .tex file, the bibliography file, figures and style files in one folder, then compress that folder into a single archive. This gives the translator the full context, including the file that holds your references.
Open omnidoc.top and upload the archive. Choose the LaTeX source package option. Uploading the whole project rather than only the body file keeps the citation keys and bibliography file connected to the text that cites them.
Choose the output format. Pick bilingual side-by-side output if you need the original and translation together, or translation-only output if you want a single translated version. For a reference list, bilingual output makes it easier to check each entry against the original.
Set the style that matches your field. OmniDoc offers style options for academic, legal, medical, technical, business and literary text. Choose the academic option for a research paper or thesis, so the terminology in the body and references is handled in a more consistent way.
Run the translation and download the result. When the job finishes, download the returned files. Keep them in a separate folder from your original project so you never overwrite your source.
Restore any entries you want kept as-is. Open the returned bibliography file and compare it with your original. Put back the original titles, DOIs, URLs and author names for any entry where the translation would change the meaning or the lookup path.
Compile the translated project. Build the document with your usual LaTeX setup. Look at the log for undefined citation warnings and missing reference errors. A clean build is the first sign that the translation did not break the links.
Compare the outputs side by side. Open the original PDF and the new one and check the reference list section by section. The checks in the next section tell you what to look for.

Check the result

Compiling without errors does not prove the references are correct. Work through these checks, then fix anything that fails.

Check	How to see it	If it's wrong
Citation keys are unchanged	Search the translated `.tex` files for a few keys from your list	Restore the original keys in both the body and the bibliography file, then recompile
Every citation resolves	Look for "undefined citation" or "?" in the compiled PDF	Check that the bibliography file was returned and that its name matches the `\bibliography` command
Reference count matches	Count the entries in the original and translated reference lists	Look for entries that were merged, dropped or split, and restore them from your backup
DOIs and URLs are intact	Click or copy a few DOIs and confirm they point to the right works	Replace any altered identifier with the original value
Names and venues are correct	Compare author names and journal or conference names with the original	Restore the original spelling; names and venue titles should not be translated
Formulas and symbols survive	Check any math inside titles or notes against the original	Re-enter the original symbols by hand
Ordering and numbering match	Compare the order of numbered references in the body and the list	If the order changed, recompile twice and check the citation style settings

Machine translation can make mistakes, and reference entries are a place where small errors matter. Read every entry you plan to submit or share, especially names, years, volume numbers and page ranges. Treat the translation as a draft that you verify, not a finished bibliography.

❓ FAQ

1. Should I translate the titles of cited papers?

Usually not, if the goal is a working reference list. The title is how readers and databases find the original work. For a bilingual list, keep the original title and add a translation in brackets, so both are visible.

2. Will changing the bibliography break my citations?

It can. The body text refers to each entry by its citation key, so a changed key means a citation no longer points to its entry. Check the keys first and restore any that were altered.

3. Can I translate only the reference list, not the whole project?

If your reference list lives in its own file, you can run only that file through the translation step and merge the result back. Keep the original keys and check the compile afterward. Running the whole project is simpler when the body and references are tied together.

4. Why does my PDF show question marks where citations should be?

Those question marks mean the citation could not be resolved, usually because the bibliography file was not found, a key was changed, or the bibliography was not compiled. Check the log for the exact warning and fix that link.

📝 Summary

Translating a LaTeX bibliography works well when you separate what should be translated from what must stay exact. Keep citation keys, DOIs, original titles and names unchanged, then compile and compare the output against your backup. A clean build and a matching reference count show the structure survived, but you should still read each entry yourself.
