RefWorks is a web-based bibliography and database manager belongs to ProQuest that allows you to create a personal, searchable database of citations. These citations can be formatted into your Microsoft Word documents as footnotes or a custom bibliography. Because it is entirely web-based (i.e. the bibliographic records reside on the web, not on your computer), it gives you access to your bibliographies from Mac, PC, or UNIX, as long as it’s connected to the Internet. RefWorks also offers a mobile platform.
Zotero is the only research tool that automatically senses content in your web browser, allowing you to add it to your personal library with a single click. Whether you’re searching for a preprint on arXiv.org, a journal article, a news story, or a book from your university library catalog, Zotero has you covered with support for thousands of sites.
