Hallo Barney,

the workaround consists of 99 lines of source code. The way I got
things to work is as follows:

1) In my document preamble I use

\usepackage[square,comma,numbers,sort&compress]{natbib}
\usepackage{mynatbib}

where "mynatbib" is the following text:

% Begin of mynatbib.sty %
\makeatletter
\AtBeginDocument{\def\NAT at sort{2}}

% End of mynatbib.sty %

I got this code from Jens Berger <jberger at gmx.net>, whose homepage is
http://userpage.fu-berlin.de/~jberger, and I saved the text as
"mynatbib.sty" in a folder where pdfLaTeX could find it.
Without this code one gets sorted, but not compressed references. At
present, I haven't got enough time to understand why; I'm happy that
things work and don't think about the reasons.

2) Within my document, I used

\bibliographystyle{unsrt}
\bibliography{Literatur/Dissertation}

"Dissertation.bib" is my literature database, which is set up in a
very uncommon manner. I think this is the reason, why I have to use
"unsrt" instead of "unsrtnat": With "unsrtnat" it doesn't work in my
case, but perhaps it does in your case.

Good luck!
