The Revision Note field in the edit resource display is an optional field that allows you to better describe the changes you have made.  

The content that you enter in the Revision Note field will be displayed in the resource’s Revision History. To see the history:

1. Select the resource you would like to view.
2. Click the Information Tab
3. Click “Revision History” at the top right of the tab display.

The page will reload to display a table of all the changes made to the resource. If you have entered a Revision Note, it will appear in the “Note” column. If you did not enter a revision note, a generic note is created by the system. We recommend that you use this field, particularly when collaborating with other users or editing other members content, in order to better detail out the changes that were made to the resource.
