OpenOffice and LibreOffice both offer EndNote 21 compatibility in the Writer word-processing app.

You will need to make sure no OpenOffice or LibreOffice products are running in the background when you install EndNote. On a Windows PC, this may require opening the Task manager to find any applications running under Apps and hitting End Task.

The EndNote menu in Writer is simplified, compared to the version in Word, but is still adequately functional.

The two most prominent things to note are:

• Format Bibliography is the Writer equivalent of Update Citations and Bibliography in Word, and
• instead of having the options to Unformat Citations or Convert to Plain Text under Convert Citation and Bibliography, Writer only has the option to Unformat Citations. You cannot convert a Writer document to plain text.

This tutorial focuses on using EndNote 20 and Apple Pages. It is still current for EndNote 21

You can use EndNote's Format Paper function with any Word processing program/app that allows you to save the document in RTF or OTD format.

In EndNote, copy the record you want to use (Edit > Copy or Ctrl+C). Paste this next to the text where you wish the in-text citation to appear.

Make sure you keep the entire formatting of the copied reference code, including the {braces}.

Once you have finished adding all of your references, save the document as an RTF or OTD file.

In EndNote, go to Tools > Format paper > Format paper... and search for the docment. When you open the document, you will see a dialogue box asking you to chose an output style. Select the style, then hit format.

EndNote will create a new file with plain-text formatting, with in-text and reference lists formatted. The references will need to be checked for any problems or inaccuracies and fixed manually.

N.B. This method does not work well with styles that require the in-text citation to be placed in a footnote, e.g. Chicago
