Zotero - is reference management software. Zotero is used to manage bibliographies and references when writing essays and articles. On many major research websites such as digital libraries, PubMed, Google Scholar, Google Books, Amazon.com, and even Wikipedia, Zotero detects when a book, article, or other resource is being viewed and with a mouse click finds and saves the full reference information to a local file. If the source is an online article or web page, Zotero can optionally store a local copy of the source. Users can then add notes, tags, and their own metadata through the in-browser interface.
