I am wondering if this is possible, I would like to cite a reference
in the body e.g [1] and at the end have the references in full e.g [1]
author, title, year e.t.c
I am wondering if there is a way whereby, if I were to add an
additional reference at the end, before or after my initial reference,
if my initial reference of [1] will automatically change in the text
body of my report?
so e.g if I added another reference [2] but I added a third in front
of reference [1] so it now becomes [2] if there is a way in word 2003
this automatic changes can take effect
