Zotero is a free, open-source bibliography platform where you can store data and then export it in any bibliographical format you need. If you download the web browser plugin, you can add sources directly from the UCLA online catalog (and many others). Tutorials and documentation are available through the Zotero website, and you can also contact me for an in-person consultation on using it for your research.
Zotero [zoh-TAIR-oh] helps you collect, organize, cite, and share your research sources. It lives right where you do your work—in the web browser itself. Zotero automatically senses content, 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 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. Zotero collects all your research in a single, searchable interface. You can add PDFs, images, audio and video files, snapshots of web pages, and really anything else. Zotero automatically indexes the full-text content of your library, enabling you to find exactly what you're looking for with just a few keystrokes.
It's supported by the Roy Rosenzweig Center for History and New Media at George Mason University.
