Hi hans, hi Taco, hello all, I used the following in my thesis (2 years ago) to make sure I won't miss a unresolved reference: --------------------------------------------------- \def\unknownreference{~~~~~\clap{\blackrule[width=1.5ex,height=1.5ex,depth=0.3ex]% \kern-0.3ex$\blacktriangleright$~~~~}% \normalunknownreference} \def\dummyreference{$\blacksquare$} --------------------------------------------------- which produced for unresolvable references: "#>myRef#" or "#>#". This does not work anymore. I only get "#myRef". How should one do it nowadays? * * * In m-bib, actually not \unknownreference (or \dummyreference) but a simple '??' is used (not even bold. It would be great if this could be changed. (search for "{??}" and ' ??\else'.) Tobias
