Other Bibliography Symbols in Beamer

I make a presentation with Beamer and I would like to change the symbols before one bibitem. Now it looks like that:

documentclass{beamer}

begin{document}

frame{frametitle{Literatur}
    begin{thebibliography}{10} 
        bibitem{1}
        Nathan Ida: Engineering Electromagnetics, Springer Spektrum, 2015, Third Edition
    end{thebibliography}
}


end{document}

How can I change it to a book or an "internet" symbol?

Thanks.
