You can copy items from one collection to another collection. Copying
items does not create additional objects; it just links the same object
to both collections.
Before you begin: View the list of items in the collection that currently contains the items
you want to copy. See Listing Collections.
From the list of items, check the ones you want to copy to a different
collection.
Click Copy To in the page Actions menu or toolbar.
Click the button for the collection where you want the items to be copied
to.
