To copy pages between documents
When you copy a page or spread from one document to another, all of the items on the page or spread, including master page objects, are copied to the new document.
Open both documents.
In the Pages palette, select the icon of the page or spread you want to copy.
Drag the icon to the other document’s window. The page or spread is added to the end of the document.
Note: If the page or spread you are copying contains paragraph or character styles, layers, or masters with the same names as their counterparts in the new document, the new document’s settings are applied to the page or spread instead.
