If you've been using Instant Formatting, each chapter will have formatted in-text citations like this: (Jones, 1957), with a bibliography at the end of each chapter.
Windows: Select Convert Citations and Bibliography > Convert to Unformatted Citations.
Note: when you unformat citations it disables Instant Formatting in Word. If you would like to restore this, on the EndNote tab click on the small down arrow to the right of Bibliography so you can change your preferences. When the dialogue box opens up, click on the Instant Formatting tab, click on Turn On and then on OK.
When you are ready to submit your thesis the final step is to remove the EndNote field codes. These codes link your documents with your EndNote library.
Note: This is not your thesis_master.doc. Should you need to make any changes to your references after this you must use thesis_master.doc which is still linked to EndNote. Then repeat the steps above.
