A subscribed library synchronizes the content from the source local content library that is published. We have two options available while creating a subscribed library:

• Download all library content immediately
• Download library content only when needed

The Download all library content immediately option initiates a synchronization process from the source library datastore to the destination library datastore. This process copies the entire content once the library creation task is complete.

The Download library content only when needed option creates a catalog of the library items of the source library, in other words it creates a catalog or metadata of information available in the source library.

You may choose to download only necessary content when required and subsequently delete the item from the subscribed library to conserve storage space.
