About this extension

Save references to Zotero from your web browser

Read the publisher’s full description

Save references to Zotero from your web browser Zotero is a free, easy-to-use, open-source tool to help you collect, organize, annotate, cite, and share research. The Zotero Connector automatically senses content as you browse the web and allows you to save items to Zotero with a single click. If a PDF is available, the Connector can save it to your library to read later, and it can even save snapshots of webpages in case they change or disappear. Whether you're searching for a preprint on arXiv.org, a journal article from JSTOR, a news story from the New York Times, or a book from your university library catalog, Zotero has you covered with support for thousands of sites. Additionally, if you use a web-based proxy to access resources your institution subscribes to, the Zotero Connector can automatically redirect you through the proxy when you follow links to those sites from elsewhere on the web, making sure that you always have access to PDFs and other gated content. While the Connector can save most pages directly to your zotero.org account, for the full Zotero experience be sure to install the Zotero desktop app, which allows you to organize your references efficiently, insert citations automatically into Word, LibreOffice, and Google Docs, and much more. You can download Zotero for free from https://www.zotero.org/download We are happy to help with any issues you encounter with the Zotero Connector, but we cannot do so through the Edge Add-ons site.
