 We also need to find which bibliography file that key is in. For that, we need to know which bibliography files are referred to in the file. If none are specified with a bibliography link, we use the default bibliography. This function searches for a bibliography link, and then the LaTeX bibliography link. We also consider the addbibresource link which is used with biblatex.
