The referencing style you use is called an “Output style”. EndNote comes with a large number of preloaded styles, but you can also add new styles, e.g. harvard-cqu. Once they are added to your library, you can select them for use in EndNote and Word.
Once an Output Style file is saved to EndNote, you can use it in your Word document.
EndNote has quite a large number of Output Styles already installed, however you may find that you need a style that is not already included.
When you add a new output style to your library, it is saved to a folder on your computer. If you are using your library on more than one computer, and you need a style that wasn't included in the original installation, you will need to save that output style file to each computer separately.
There are 2 locations for your Output Styles folders:
To check your folder locations in EndNote, go to the Edit menu > Preferences > Folder Locations.
Styles folder location:
To check your folder locations in EndNote, go to the EndNote 20 menu > Preferences > Folder Locations. (If you are using a different version of EndNote, that number will be in the menu name.)
