== Unlinking subjects ==
Unlinking a subject does not change any EPrint records, in fact it does not even change the subject record, it just unsets the current parent subject for that record.  However, if you unlink a subject you will need to remember its subject ID string so you can re-link it (see above).  Unlinked subjects will stop it being displayed for an EPrint abstract/summary page if this is regenerated.  It will also display in the form '''?? E151 ??''' in the EPrint workflow to indicate you have a subject set that does not have a subject linked into the tree.

If you need to make changes to you divisional structure you may need to move subjects around.  It is advised that you link a division under its new parent division before unlinking it from its current parent division.  In theory you can do this the other way round but you will probably feel safer doing it the first way or you will get a message warning you that you are permanently removing the subject, which sounds a bit more serious than it actually is.

Unlinking a subject is very easy.  If you are unlinking a subject that is link elsewhere in the tree, it will be unlinked as soon as you click on the '''Unlink''' button next to the relevant child subject.  If it is not link elsewhere you will be asked to confirm the unlinking.
