Citation Management, or Reference management, tools are easy-to-use tools that can help you collect, organize, cite, and share research sources. Examples include Zotero, Mendeley, EndNote, RefWorks, and EZbib.
Most Columbia databases allow you to export full citations, and sometimes PDFs, into Citation Management tools, and many citation management tools have web plugins to help capture website information.
Zotero and Mendeley are both free softwares, and EndNote is free for all current Columbia & Barnard students. All require the creation of an account to use, and have both standalone downloadable versions as well as web versions.
Check out the Barnard Library's Guide to Citation Management to compare softwares and learn more.
