Hallo,
das dürfte eigentlich wirklich keine Probleme machen:
Code:
\documentclass{article}
\begin{filecontents}{lit1.bib}
@article{Dempster:1977aa,
Author = {A.P. Dempster and N.M. Laird and D.B. Rubin},
Journal = {Journal of the Royal Statistical Society, Series B},
Keywords = {EM},
Number = {1},
Pages = {1--38},
Title = {{Maximum Likelihood from Incomplete Data via the EM Algorithm}},
Volume = {39},
Year = {1977}}
\end{filecontents}
\begin{filecontents}{lit2.bib}
@article{Moon:1996aa,
Author = {T.K. Moon},
Journal = {{IEEE} Signal Processing Magazine},
Keywords = {EM},
Number = {6},
Pages = {47--60},
Title = {{The Expectation-Maximization Algorithm}},
Volume = {13},
Year = {1996}}
\end{filecontents}
\begin{document}
\nocite{*}
\bibliographystyle{plain}
\bibliography{lit1,lit2}
\end{document}
Ansonsten erstell mal bitte ein (kompilierbares) Minimalbeispiel.
