Question on Table of Authorities in MS Word?

What I would like to achieve is a text looking sort of like this:

'It's been demonstrated that different types of water have a profound effect on a human being [1], [2]. My studies include experiments ... blah blah."

At the very end of my (very long) document I would like to list the sources in the following form:

[1] J. Doe "Miracle of Water", 1997

[2] C. Smith "Benefits of proper hydration, 1985

How to I do that?

Now, if I were to add another source which supposed to fit in between these two sources according to alphabetic order, say a book written by S. Johnson, the numbering will have to change. How do I make them change automatically, so that I don't have to go through entire text and change tem by hand?
