zApps or books that you no longer wish to view in ‘MY LIBRARY' can be archived. Archiving does not delete the zApp or book, as this action would also delete any results connected to it, but removes it to the ‘Archived zApps’ or ‘Archived Books’ tab where it remains out of the way until such time as you may like to un-archive it.
To archive a zApp or book, click the red cross next to its name.
To un-archive a zApp or book, click the archived tab and select the un-archive button from the action column.
