Keep each chapter document separate until the very end when you no longer wish to make any changes to your EndNote references.

1. Create a blank document where you will place all the chapters.
2. Make a backup copy of all the documents you wish to merge.
3. Open each chapter document.
4. Copy the text of the individual documents, but NOT the reference list. It is important that you do not include the reference list as part of what you copy.
5. Paste the text from the individual documents into the new blank document
6. Once you have created the merged document, Click the EndNote tab and click Update Citations and Bibliography.

This procedure will create a formatted Microsoft Word document with one bibliography at the end.
