I am using multibib with two bib-files. For the first one I use a numeric citation style. But for the second one I want to have [A1, A2, ...]. This works for my reference list but in my citation I still have [1, 2, ...]. How can I change this to [A1, A2,...]?

Here is my minimal document (you have to use 2 bibfiles: litA and litB)

\usepackage[ngerman, english]{babel}
\usepackage{textcomp} %\textmu einfügen z.B.
\usepackage[normalem]{ulem}     %text unterstreichen, durchstreichen usw.

Welcome to TeX.SX. A tip: If you indent lines by 4 spaces, then they're marked as a code sample. You can also highlight the code and click the "code" button ({}) or select your code and hit Ctrl+K. – Claudio Fiandrino Feb 22 '13 at 15:51

multibib doesn't remove the ordinary citing mechanisms, merely adds additional commands to them. Thus for the bibliography items that should not have label prefixes you can use an ordinary \cite command, combined with usual \bibliographystyle and \bibliography, and simultaneously you can use multibib with the [labeled] option to set up another cite style \citeA with prefix A and with \bibliographystyleA and \bibliographyA. Note the prefix is constrained to be the same as the extension to the name of these commands. Here is a cut-down example:

Sample output




Reference without prefix \cite{bb} and a reference with prefix \citeA{aa}.




with lit.bib containing

  author =   {Author, A.},
  title =    {Title},
  journal =  {Journal},
  year =     2000

  author =   {Brother, B.},
  title =    {Titling},
  journal =  {Ann. J.},
  year =     2002

Thank you for this information. My problem is that I need several bibliographies (one per chapter), each starting with [A1]. Is this possible? – user26342 Mar 18 '13 at 6:40
That is a rather different question, and should perhaps be asked as such. chapterbib will mostly likely be able to do that for you; its \citeform command will allow adjusting the style of citations. – Andrew Swann Mar 18 '13 at 7:20
