Zotero [zoh-TAIR-oh] is a free, easy-to-use tool to help you collect, organize, cite, and share your research sources. As you search, use Zotero to collect sources with one click from online catalogs (e.g. BC Library Catalog, WorldCat) and databases (e.g. JSTOR), as well as websites like Amazon, newspapers, blogs, Flickr, and YouTube. While you write, use Zotero to create in-text citations and bibliographies directly inside your Microsoft Word document from your personal library of references. Developed by the Center for History & New Media at George Mason University.
Bibliographies allow you to follow an author's sources backwards in time. By definition, anything cited in a book or article will have been published prior to that book or article.
Citation tracking allows you to move forward in time, following who has cited that book or article since its publication. You can deduce how influential a specific source has been and follow the scholarly conversation around a specific topic.
