Word should be able to transform footnotes into a bibliography.

[johnny appleseed]

It would make things amazingly more simple if word was able to automatically
create a works cited or bibliography page, based on footnotes throughout the
document.

 

[Klaus Linke]

You could write a macro to do that. It would depend on your bibliography's
scheme and the footnotes, though... and that would need to be very consistent.
There'll probably never be a built-in solution.
Maybe you can find a wizard or some other macros to help with creating the
bibliography. Old versions used to have something like that (say in
Macros9.dot from Word2000).
