Thanks to your help, I managed to get a structured bibliography done with
all the features I need using bibtopic.
However, I have two remaining problems:
1) It only works if I run latex/bibtex on the exported tex file manually.
>From within lyx I just get unresolved references and an empty bibliography.
I can't even insert references with the lyx popup but have to put it in ERT.
2) Cross-refs between different bibfiles do not work (they just do not
appear). In case bibtopic is not the right package for this (the
documantation seems to say so), is there any other way for achiving this?
Does anyone has expiriences with multibib which is mentioned in the bibtopic
docs?
Thanks for your help.
