2. From within your EndNote Library
- Select the citation(s) you wish to insert, and click on "Insert Selected Citation(s)

In Word, you will notice that your citations and reference list are automatically formatted in whichever style is selected. To change the style, choose from the styles in the EndNote tab's style menu; click on "Select Another Style" to see an expanded menu of options.
