Zotero is a reference manager: a library for every book, article, score and web page you read, and a way to cite them without retyping a bibliography ever again. ## What it does - **Saves sources in one click.** A browser extension captures the citation details, and often the PDF, from a library catalog, journal or web page. - **Keeps your reading in one place.** PDFs open in Zotero’s own reader, where highlights and notes stay with the source. - **Cites for you.** Plugins for Word and Google Docs insert citations and build the bibliography in thousands of styles, Chicago and APA among them, and change style in a click. - **Organizes flexibly.** Collections and tags let one source belong to several projects at once. ## Cost Free and open source, developed by a nonprofit, the Corporation for Digital Scholarship. Syncing your library is free, with a small amount of free storage for files; more storage is a paid subscription, which funds the project. Website: [zotero.org](https://www.zotero.org)
