## Introduction
Zotero is a free, open-source reference manager designed for researchers, students, and anyone who needs to collect and organize sources. It captures bibliographic data from websites, library catalogs, and academic databases with a single click, stores PDFs and annotations alongside metadata, and generates formatted citations and bibliographies in thousands of citation styles. Zotero is developed by the Corporation for Digital Scholarship, a non-profit organization.

## What Zotero Does
- Captures bibliographic metadata from web pages, databases, and library catalogs via a browser connector
- Stores, organizes, and tags references in a local library with collections and smart folders
- Provides a built-in PDF reader with annotation, highlighting, and note extraction
- Generates in-text citations and bibliographies in over 10,000 citation styles (CSL)
- Syncs libraries across devices through Zotero cloud storage or WebDAV

## Architecture Overview
Zotero is built on a custom XUL/JavaScript framework that shares heritage with Firefox. The local library is stored in a SQLite database alongside file attachments. The browser connector communicates with the Zotero desktop app through a local HTTP server to save items. Citation generation uses the Citation Style Language (CSL) processor, which parses CSL XML style definitions to format references. Word processor plugins inject citations through a document-field-based API.

## Self-Hosting & Configuration
- Download desktop installers from zotero.org for Windows, macOS, and Linux
- Install the Zotero Connector browser extension for one-click saving from the web
- Configure Zotero sync for free cloud storage (300 MB) or point to a self-hosted WebDAV server for file storage
- Word processor plugins are available for Microsoft Word, LibreOffice, and Google Docs
- Extend functionality with community plugins for Better BibTeX, Zotfile, ZotMoov, and more

## Key Features
- Browser connector saves references from academic sites, Amazon, news outlets, and more with one click
- Built-in PDF reader with highlights, annotations, and automatic metadata extraction
- Group libraries enable collaborative reference sharing among research teams
- Better BibTeX plugin provides stable citation keys and automatic BibTeX/BibLaTeX export
- Related items and tags create a navigable web of connected references

## Comparison with Similar Tools
- **Mendeley** — Similar feature set but owned by Elsevier with privacy concerns; Zotero is independent and open source
- **EndNote** — Established commercial tool used in many institutions; Zotero is free with comparable citation features
- **Paperpile** — Cloud-native with a clean UI; Zotero offers offline access and stronger community plugin ecosystem
- **JabRef** — BibTeX-focused and open source; Zotero has broader format support and a more user-friendly interface
- **Citavi** — Popular in German-speaking academia with knowledge organization tools; Zotero is free and cross-platform

## FAQ
**Q: Is Zotero really free?**
