Referencing styles

Referencing (Output) styles

EndNote referencing (output) styles determine how a reference will be formatted and displayed in your reference list. A different reference style, e.g. APA 6th, Chicago, MLA, JAMA & other styles used by individual journals, can easily be selected to display the same list of references in a different style.

EndNote is installed with 200+ output styles, with another 5,000+ styles available from Clarivate Analytics


Referencing styles

EndNote output styles are based on established referencing styles, such as that used by the American Psychological Association (APA), MLA, Chicago and the instructions for authors provided by individual publishers.

In order to use EndNote effectively, you should to be familiar with CSU referencing requirements and the referencing style used by your School.

Installing individual styles

  1. Apply the EndNote style finder at Clarivate Analytics™ to locate latest version of the required style
  2. Download the style that you want to install

Endnote styles

  1. Select File > Save As
  2. Click on File > Close Style

If you are updating an existing output style EndNote will append the word ‘Copy’ to the name of the file. You might like to change this to something more meaningful, e.g. Oikos 2018_February_24.ens

Creating & editing styles

If an existing output style does not meet your publishing needs, you can edit an existing style (preferred option) or create a new style. You can change such things as the way the author(s) name is displayed, the order of references in a bibliography, or how references are formatted.
