Something like: [...] 0 is an integer literal, not a string, for entry Yang:Angliz90 while executing---line 1558 of file hempen.bst You can't pop an empty literal stack for entry Zizek92 while executing---line 1558 of file hempen.bst (There were 437 error messages) BTW, according to de.comp.text.tex, such errors should be easily reproducable with this stylefile: http://www.ctan.org/tex-archive/biblio/bibtex/contrib/german/din1505/natdin.bst Jürgen.
