如何在 beamer 中引用多个来源的参考文献？

Question

我想引用不同文件名的参考文献。为了清楚起见，假设我的一些参考文献保存为，myref1.bib而另一些则位于名为的文件中myref2.bib。如果我想引用第一个文件中的参考文献，我可以使用

 \bibliography{myref1.bib}

那么，如何引用这些内容myref2.bib？非常感谢！

Answer 1

您可以在宏中使用逗号分隔的文件列表\bibliography：

\documentclass{beamer}

\begin{filecontents*}[overwrite]{myref1.bib}
@article{einstein,
    author = {Einstein, A.},
    title = {Die Grundlage der allgemeinen Relativitätstheorie},
    journal = {Annalen der Physik},
    volume = {354},
    number = {7},
    doi = {10.1002/andp.19163540702},
    pages = {769--822},
    year = {1916}
}
\end{filecontents*}

\begin{filecontents*}[overwrite]{myref2.bib}
@book{knuth,
  author       = {Knuth, Donald E.},
  title        = {The {\TeX} book},
  date         = 1984,
  maintitle    = {Computers \& Typesetting},
  volume       = {A},
  publisher    = {Addison-Wesley},
  location     = {Reading, Mass.},
  langid       = {english},
  langidopts   = {variant=american},
  sortyear     = {1984-1},
  sorttitle    = {Computers & Typesetting A},
  indexsorttitle= {The TeXbook},
  indextitle   = {\protect\TeX book, The},
  shorttitle   = {\TeX book}
}
\end{filecontents*}



\begin{document}

\begin{frame}
\cite{einstein}\cite{knuth}
\bibliographystyle{plain}
\bibliography{myref1,myref2}
\end{frame}

\end{document}
