Zotero facilitates the management and formatting of citations. However, like other citation management software tools, it is vital that you check the citation data at the import stage, the formatting of your in-text citations, and the generated bibliography to ensure the completeness and accuracy of the data captured or the references being produced. Sometimes, if there were entry errors for your resources' metadata, those same errors could be replicated in your in-text citations and/or bibliographies.
Zotero can automatically create and update bibliographies and format citations (in-text, footnotes) in a variety of citation styles in your document by installing Zotero's plugins for word processors such as Microsoft Word, LibreOffice or Google Docs
If all you need to do is create a list of references to email to someone or post to a website, it is not necessary to use a word processor plugin. You can create a bibliography directly within Zotero.
