EndNote Online is free to use. Although EndNote Online is web-based it can be used with the EndNote desktop application. EndNote desktop software must be purchased but is offered at a reduced rate through the University's site license. Please contact the IT Service Desk for information about purchasing the software.
You can access EndNote Online from http://my.endnote.com/.

EndNote Online has a plug-in feature called Cite While You Write which allows you to add references and citations directly into the Word file of your essay or piece of work.
You need to install a plug-in which adds Cite While You Write to the Word toolbar. Information about installing the plug-in can be found on the EndNote Online help pages.
