OneCite is a command-line tool and Python library for citation management. It accepts DOIs, paper titles, arXiv IDs, and mixed inputs, and outputs formatted bibliographic entries.
Researchers frequently accumulate reference lists in ad-hoc formats — DOIs copied from browser tabs, arXiv IDs from paper PDFs, titles typed by hand, and BibTeX fragments from various sources. Cleaning these into a consistent, complete .bib file is tedious and error-prone.
OneCite solves this by accepting any mix of identifiers and text queries and automatically resolving them to structured BibTeX through a pipeline of academic APIs (CrossRef, arXiv, PubMed, Semantic Scholar, and others). It is designed for researchers who work primarily in the terminal, use LaTeX, and want a lightweight, scriptable tool — not a full reference manager.
When to use OneCite vs. alternatives:
| Tool | Best for |
|---|---|
| OneCite | One-shot conversion of messy reference lists to BibTeX in a terminal/script |
| Zotero | Long-term reference management, GUI-based, browser integration |
| CrossRef API directly | When you have clean DOIs and want canonical metadata |
| doi2bib | Single DOI → BibTeX conversion, no fuzzy matching |
| Feature | Description |
|---|---|
| Fuzzy Matching | Match references against multiple academic databases even from incomplete or inaccurate info. |
| Multiple Formats | Input .txt/.bib → Output BibTeX. |
| 4-stage Pipeline | A 4-stage process (clean → query → validate → format) to produce consistent output. |
| Field Completion | Enrich entries by filling in missing fields like journal, volume, pages, authors, and abstract. |
| 🎓 7+ Citation Types | Handles journal articles, conference papers, books, software, datasets, theses, and preprints. |
| Multi-Source Lookup | Queries CrossRef, arXiv, PubMed, Semantic Scholar, Google Books, and others for every entry. |
| Many Identifier Types | Accepts DOI, PMID, arXiv ID, ISBN, GitHub URL, Zenodo DOI, or plain text queries. |
| 🎛️ Interactive Mode | Manually select the correct entry when multiple potential matches are found. |
| Custom Templates | YAML-based presets that provide a fallback BibTeX entry type when auto-detection is inconclusive. |
Install and try OneCite in a few steps.
# Recommended: Install from PyPI
pip install onecite
Create a file named references.txt with your mixed-format references:
# references.txt
# Add blank lines between entries to avoid misidentification
