# pybtex — A BibTeX-compatible bibliography processor in Python

License: permissive · Maintenance: active · Downloads: 1.9M/mo

## What it is and what it does

Pybtex is a Python implementation of a BibTeX bibliography processor that bridges LaTeX document workflows with programmatic bibliography management. It reads citation data from multiple formats—BibTeX (.bib files), BibTeXML, or YAML—and produces formatted bibliographies in several output formats including LaTeX, HTML, markdown, and plain text. The package supports both traditional BibTeX style files (.bst) and custom styles written directly in Python, making it useful both as a command-line tool (as a drop-in replacement for the bibtex command in LaTeX workflows) and as a library for Python scripts that need to manipulate or generate bibliographies.

The package depends on importlib-metadata for version discovery, latexcodec for LaTeX character encoding support, and pyyaml for parsing YAML-formatted bibliography data. It is actively maintained, supports modern Python versions (3.8+), and carries no known security vulnerabilities. The MIT license permits use in both open-source and proprietary contexts.

Use it for:

- Automate bibliography generation in LaTeX documents as part of a build pipeline without invoking the bibtex command.
- Convert BibTeX files to HTML or markdown for web-based publication or documentation sites.
- Parse and programmatically manipulate citation data (add, filter, or reformat entries) in Python scripts.
- Generate bibliographies in custom formats by writing Python-based citation styles instead of .bst files.
- Integrate bibliography processing into Python-based document generation or academic publishing workflows.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Pybtex reads bibliography data from BibTeX, BibTeXML, or YAML files and generates formatted bibliographies in LaTeX, HTML, markdown, or plain text, supporting both BibTeX style files and Python-based custom styles.

Yes. Pybtex is a mature, actively maintained tool with low install friction, no security vulnerabilities, and a permissive license. Install it if you need to process BibTeX files programmatically, generate bibliographies in multiple formats, or integrate bibliography handling into a Python workflow. It is particularly valuable for automating LaTeX bibliography workflows or converting citations to web-friendly formats.

## Install

pip install pybtex
uv add pybtex
poetry add pybtex

## Installing pybtex

Before you install: Low install friction with three lightweight runtime dependencies (importlib-metadata, latexcodec, pyyaml). Active maintenance with a release 133 days ago. Supports current Python versions (3.8+).

License in practice: MIT license permits free use, modification, and distribution with minimal restrictions, making it suitable for both open-source and commercial projects.

Quickstart:

pip install pybtex

from pybtex.database import parse_file
bib_data = parse_file('references.bib', 'bibtex')
print(bib_data.entries)

Requires Python 3.8 or later; LaTeX installation recommended if using LaTeX output format.

Verify before relying:

- Whether BibTeX style file compatibility covers all common .bst files or only a subset
- Performance characteristics when processing large bibliographies (thousands of entries)
- Whether markdown output preserves citation metadata or produces plain text references
