You can add other people as collaborators to your lists, to allow them to add and edit items. 

Click on the List info link at the top of reading list and click Manage collaborators.

If you no longer need to be a collaborator of a list, use the Manage collaborators option to remove yourself from the list. If you are the list owner, you cannot delete yourself from the collaborators list. Make another user the list owner and then remove yourself. Do not delete your list. This will delete the list for all users and cannot be restored by the library staff.
