Hi Jünger:
"Look at the preamble: you will have to adapt the paths in the \bibliography command to point to the locations of your *.bib files. In your original files, you used non-valid paths, which was probably the reason it did not work for you." OK, I've just correct the path to the bibliographies in the preamble and in the bibliography inserted into the text. The .bib files are are into the folder texmf/bibtex/bib and I've run texhash. Also the script is in the same folder and the latex command is now bibtexall. But, when I make an output by pdflatex, the bibliographies doesn't appears!. What happens? regards Antonio
