This comprehensive coverage ensures that users can format their citations and bibliographies according to the specific requirements of their field or publication. If a specific citation style is not available in Zotero's library, users can easily create and modify custom styles using the Citation Style Language (CSL), an open-source formatting language.
• Word Processor Integration: Zotero seamlessly integrates with popular word processors, including Microsoft Word, LibreOffice, and Google Docs. Through these integrations, users can effortlessly insert citations and generate bibliographies directly within their documents. As users write and add citations, Zotero automatically updates the bibliography in real-time, ensuring that it remains consistent and accurate throughout the writing process.
