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.

Statement of Need

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.

Quick Start

Install and try OneCite in a few steps.

1. Installation

# Recommended: Install from PyPI
pip install onecite

2. Create an Input File

Create a file named references.txt with your mixed-format references:

# references.txt
# Add blank lines between entries to avoid misidentification

3. Run OneCite

Execute the command to process your file and generate a clean .bib output.

onecite process references.txt -o results.bib --quiet

4. View Output

Your results.bib file now contains entries of different types.
