An easy-to-use web-based bibliographic management tool to help you collect, organize, cite, and share your research sources. This tool works within your web browser; you can download plug-ins so that you can also use it while working within word processing software.
There are many other reference management tools used by researchers. Some are free, some are not. Some of the more well known free tools (in addition to Zotero) include Mendeley, Connotea, and CiteULike.
What is a "citation style"? You are probably already familiar with the elements of a typical article citation: author, article title, journal, publication year, volume, issue, pages. The order and formatting of these elements into a citation is the citation style.
Some scientific societies have defined their own particular citation style, and most science journals have a preferred citation style. You can also consult the style guides listed below.
Commonly used style guides are listed below. (Some links go to the library's print copy, some go to online resources.)
