I am using multibib for a document with two different types of references. To this end, I have defined

\newcites{R}{Own publications}

which adds a prefix "R" to references from that group when citing with \citeR.

Does anyone know how to combine references in the form

\cite{key1,key2,key3} giving [1,2,R3]?

Not sure if a wrapper for the cite command would work?

  • This isn't so easy. cite uses \jobname.aux and citeR uses R.aux. You can do what you want with biblatex. Feb 20, 2012 at 18:29
  • Thanks. I was hoping to avoid biblatex, but maybe it is a good reason to switch from bibtex.

Problems like this one can be quite easily solved by switching to biblatex, while they are almost impossible with multibib.


I had the same problem. I found a simple work-around.

All you need is to add another bibliography that is not used in order to have a \cite command which does not add keys to either of your real bibs. Then, you can manually add the references to the bibs by using the \nocite commands. Your example will look like this:

\newcites{R}{Own publications}
\newcites{trash}{foo} % auxiliary cite command
\newcommand\mycite[2]{\citetrash{#1,#2}\nocite{#1}\nociteR{#2}} % new cite command

You will have an trash.aux file generated, but as long as this does not trouble you, it does the trick.
