Assume that I have a large bibliography file and a large document with a lot of citations. Now I want to know which works collected in the bibliography file aren't cited in my document.
Is there a way to achieve this?
P.S. I am aware of a recent article in Die TeXnische Kommödie where a partial solution of this problem is presented (basically, use an unsorted bibliography, use a sentinel for the last citation, and use \nocite{*}—all bibliography entries coming after the sentinel are not cited). There must be something better than that.
