Managing Your Bibliography with Mendeley and LaTeX

Mendeley is where a lot of researchers keep their reading. The annotated PDFs, the groups, the desktop highlights. The trouble starts when that library has to meet LaTeX, because LaTeX does not read Mendeley, it reads a .bib file. Building a clean Mendeley LaTeX bibliography means getting your library out as BibTeX and, ideally, keeping that BibTeX current as your reading grows. This guide covers both the export mechanics and a workflow where the syncing happens for you.

Mendeley to BibTeX: how the export works

Mendeley Reference Manager can write a .bib file from your library. In the older Mendeley Desktop you set this under the BibTeX options, choosing to sync your library to a single .bib file or one file per group. In the newer Mendeley Reference Manager you export a collection to BibTeX directly.

The output looks like ordinary BibTeX:

@article{shannon1948mathematical,
  author  = {Shannon, Claude E.},
  title   = {A Mathematical Theory of Communication},
  journal = {The Bell System Technical Journal},
  year    = {1948},
  volume  = {27},
  number  = {3},
  pages   = {379--423}
}

@book{cover2006elements,
  author    = {Cover, Thomas M. and Thomas, Joy A.},
  title     = {Elements of Information Theory},
  publisher = {Wiley-Interscience},
  year      = {2006},
  edition   = {2}
}

Two things to watch. First, Mendeley’s citation keys are not always the prettiest, and they can shift if you change author or year fields, which breaks any \cite{} already in your document. Decide on a key and leave it alone. Second, check the BibTeX entry type. A conference paper saved as a generic document can export as the wrong type and confuse your bibliography style.

The export-once trap

Doing this once is fine for a finished paper. It is painful for a living document like a thesis or a survey, where you add references for months. Every time your reading grows you have to remember to re-export, then replace the file in your project, then recompile. Forget once and you cite a paper your .bib has never heard of. The compiler responds with an undefined-citation warning, and you lose twenty minutes hunting for a problem that is really just a stale file.

This is the difference between import and sync. Import is a snapshot. Sync is a connection that stays live.

An always-synced Mendeley .bib in inscrive

inscrive connects to Mendeley and keeps an always-synced .bib in your project. Add a reference in Mendeley, and it appears in the bibliography your document compiles against. No manual export, no file swapping. You also get live citation autocomplete: type inside \cite{} and inscrive suggests keys from your synced library, so the key you insert is one that actually exists.

That sync is part of the Free plan. inscrive is freemium. The Free tier costs nothing and includes up to 10 active projects, unlimited collaborators, 60-second compile time, and both Mendeley and Zotero sync. Pro is €7/month and adds unlimited projects, 480-second compiles, and AI assistance. The reference-syncing you need for a clean bibliography does not sit behind the paywall. If you also use Zotero, our Zotero LaTeX integration guide covers the same workflow from that side.

A practical setup

1. Tidy the library before you connect

Fix obviously broken entries in Mendeley first. A missing journal field or a wrong entry type is easier to correct at the source than to patch in BibTeX later. Make sure each item has the fields your citation style needs, for example pages and volume for journal articles.

2. Connect and cite

Link Mendeley to your inscrive project. Then write normally. With BibLaTeX and the Biber backend, which handles accented author names without escaping:

\documentclass{article}
\usepackage[backend=biber,style=numeric,sorting=none]{biblatex}
\addbibresource{references.bib}

\begin{document}

Channel capacity has a precise meaning \autocite{shannon1948mathematical}.
The standard reference is \textcite{cover2006elements}.

\printbibliography

\end{document}

3. Let the bibliography update itself

As your Mendeley library grows, the synced .bib follows. Your job is to cite. The plumbing is handled.

Where your library lives, and why it matters

Your reference library is a quiet record of your research direction. Combined with unpublished drafts, it is genuinely sensitive data. So the hosting question is fair to ask: where does it sit, and under whose jurisdiction?

inscrive keeps everything on EU soil. Hosting is with Hetzner in Germany and Finland, in ISO 27001-certified data centres, with full GDPR compliance and a signed Data Processing Agreement available to institutions. There are no third-country data transfers, so you are not exposed to the Schrems II questions that follow US-hosted tools. For a university DPO weighing tools, that is often the deciding factor rather than a footnote. The details are on the GDPR page.

And because AI features are increasingly bundled into writing tools, it is worth stating plainly: inscrive never uses your documents or library to train AI models.

Sync vs import, side by side

Most editors will accept a Mendeley .bib. Fewer keep it in step with your library, and that gap is where the real time goes.

Mendeley groups and collaborative bibliographies

Mendeley groups are useful when several people read into the same project. A shared group becomes a shared reading list, and that maps naturally onto a shared bibliography. The risk is that two co-authors create two entries for the same paper, with two different citation keys, and your document ends up citing both. The reference appears twice in the bibliography and a reviewer notices.

Agree on one source. Pick a single Mendeley group or a single owner’s library as the canonical bibliography for the paper, sync that one into the project, and ask co-authors to add new references there rather than to their personal libraries. Because inscrive supports unlimited collaborators on every tier, the limit is your process, not the tool. Everyone can be in the same project; the discipline is in keeping one library authoritative.

Citation keys deserve the same agreement. If Mendeley generates keys you find unwieldy, settle on a convention early and stick to it, because changing a key after co-authors have already typed \cite{} calls against it will break their references on the next compile. A short, predictable convention like surname-plus-year saves a surprising amount of cleanup later.

A note on BibTeX versus BibLaTeX

Mendeley exports plain BibTeX, which works with both the old bibtex toolchain and the newer biblatex package with the Biber backend. For most academic writing today, BibLaTeX with Biber is the better default. It handles Unicode author names without escaping, supports more entry types like @online and @dataset, and gives you finer control over sorting and style. The Mendeley .bib feeds either one, so the choice is yours and you can switch later without re-exporting.

Common Mendeley-to-LaTeX snags

Duplicate entries are the usual culprit when the same reference shows up twice in your bibliography. Merge duplicates in Mendeley rather than editing the .bib. If special characters render oddly, switch your bibliography to the Biber backend, which is Unicode-aware. And if a citation style refuses to capitalize an acronym, brace it in the title field, for example {DNA}, so the style leaves it alone.

Write with a bibliography that keeps pace

The goal is simple. You read, you save to Mendeley, you cite, it compiles. No export ritual, no stale files, no last-minute undefined references.

Connect your Mendeley library to inscrive for an always-synced .bib with live autocomplete. Free to start, EU-hosted, GDPR compliant. Compare the plans on the pricing page.
