Citation management software allows a user to organize and retrieve information, such as citations for books, articles, and Web sites, by interfacing with library databases. The citation manager then works with word-processing software to insert properly formatted footnotes or citations into a paper and create a properly formatted bibliography.
Zotero: Zotero is a free, easy-to-use, open source research tool that runs in the Firefox web browser and helps scholars gather and organize, annotate, organize, and share the results of their research. It includes the best parts of older reference manager software (like EndNote)—the ability to store full reference information in author, title, and publication fields and to export that as formatted references—and the best parts of modern software such as del.icio.us or iTunes, like the ability to sort, tag, and search in advanced ways. Using its unique ability to sense when you are viewing a book, article, or other resource on the web, Zotero will—on many major research sites—find and automatically save the full reference information for you in the correct fields.
