Hello, Many thanks Emmanuel for your help.
Indeed, I'm using org-ref and scimax, all the nice tools that John offers very generously to the community; org-ref is so convenient that now I cannot imagine to work without it. Maybe John has the solution for future exports. (I did not succeed to export in odt because of links, bibliography links.) Finally the best result was done directly via pandoc, via a command line like this one: pandoc -s --filter pandoc-crossref --bibliography=reforg.bib --csl=ieee.csl -o mydocument.odt mydocument.org But pandoc-crossref never worked and I had also to make png images for tables. The best solution that I found was to install libreoffice-texmaths. I just had to enter "sudo aptitude install libreoffice-texmaths" via my GNU/Linux Debian sid, but for other OS, the package is here https://extensions.libreoffice.org/extensions/texmaths-1 and it works. Of course the output is less pretty than the pdf via the tex life.... I hope that it will help other people. Best wishes, Jo. PS: The publisher is in philosophy...
