title: LaTex - BibTex: Comma at the End of Citation
body: <p>When I cite something in my Latex-File the rendered citation alsways has a comma behind the last one (see the Picture)... 
  How can I make this comma disappear?

  <p>The citations in the BibTex-File all look like this:</p>
  
  <pre><code>@inproceedings{chun10,
    title={Vizcept: Supporting synchronous collaboration for constructing visualizations in intelligence analysis},
    author={Chung, H. and Yang, S. and Ma{\ss}jouni, N. and Andrews, C. and Kanna, R. and North, C.},
    booktitle={Visual Analytics Science and Technology (VAST), 2010 IEEE Symposium on},
    pages={107--114},
    year={2010},
    organization={IEEE}
  }
  </code></pre>
  
  <p>I call it as usual...</p>
  
  <pre><code>\cite{chun10}
  </code></pre>
  
  <p>And in my main document the important lines look like this:</p>
  
  <pre><code>\bibliographystyle{alpha}
  \bibliography{./Bib/frie13}
  </code></pre>
  
  <p>I included the germbib-package...</p>
  
  <p>I don't have any idea for a solution.</p>
