In addition to linking a new document into the outline, you can also reuse content by linking an existing document into the structure. There is no limit to the number of times you can reuse an existing document. However, inserting an existing document creates a link to the original document and does not create a copy of the existing document. Therefore, if you link multiple instances of the same document into your outline and then modify one instance of that document, your changes are reflected in all linked instances.
Note: You can also copy an existing document and link it to another document. When you copy a document, you have the option to link it as the original or link it as a copy. When it is linked as a copy, you can change the content of the copy without changing the content of the original document.
In addition to linking new and/or existing documents from the Outline Editor, you can also drag-and-drop or copy/paste documents from the Library into the outline. To do this, you need to split the view and open the Outline Editor in one pane and the Library in another. Then you can select one or more documents in the Library and either copy/paste or drag-and-drop them into the Outline Editor.
Note: When you link an existing document into the outline, the linked document retains its original property settings from when the document was created and does not inherit properties from its parent.
