Perhaps you could post a minimal example that doesn't work for you?

Note that this solution doesn't depend on ebib. It is perfectly OK to enter the bibliography key by hand if you prefer.

On your other observation: I don't use underscores in headlines, so hadn't run across the limitation in the cross references that you mention. I don't know if there is any way around this. If you do find a way, please feel free to add the solution to the LaTeX export tutorial.

All the best,

Tom

The code the OP cited passes desc to \cite{}. The code I pointed to
passes path to \cite{}. It does this to get around the problem of
escaped underscores, if I remember correctly. In any case, I use this
code with bibliography keys that include underscores, so it should
work for the OP.

I still don't quite understand, so obviously I'm missing something
fundamental - but I'll read your tutorial completely first (great
tutorial btw!) and try some things out.

Thomas, I also do not understand your reply, sorry. I have tried to
implement your solution with ebib, but it is not working. Well,
personally I do not use ebib, so it would be more elegant for me do
not depend on it. Anyway, I think I have to invest more time to better
understand this ebib-oriented solution to underscore.

In addition, I also find out that the cross-references
(http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-16)
do not work either when the reference has underscore in it.

Thanks,
Mauro
