The nodereference field type that allows you to create links to related content when you are creating a node. This can be used to create a parent-child connection between content nodes; in this project we use it so the client can produce a set of articles on a single topic. This functionality could also be achieved using the book module as that also allows you to string together a set of related nodes, but as we don't need book module's capacity to build a deep hierarchy this is a more user-friendly way of achieving the desired result.
