bibliography style

hi, need help to create customized citation-bibliography
style

When I have this book:
Bernard P. Zeigler: Theory of Modelling and Simulation,
Krieger
Publishing Co., Inc., 1984.

I cite it [Zeigler84] and in a bibliography list I want to
see:
[Zeigler84] Zeigler, B. P.: Theory of Modelling and
Simulation, Krieger
Publishing Co., Inc., 1984.

The problem is to include citation text as bibliography
part. And there
is no field to insert for that :-/
