I’m wondering how could I cite mi internet sources with round brackets and my other sources with square brackets. I want to replace the [] of the Wikipedia cite for ().


\usepackage[sorting=nyt,style=authoryear, backend=bibtex8]{biblatex}





\printbibliography[heading=bibintoc, title=Literaturverzeichnis}, nottype=misc]
\printbibliography[heading=bibintoc, title={Internetverzeichnis}, type=misc]

Content of Literature.bib:

  author = {Wikipedia, the free encyclopedia},
  year = {2017},
  title = {Massenspektrometrie},
  url = {https://de.wikipedia.org/wiki/Massenspektrometrie#Arten_von_Analysatoren},
urldate = {29.05.2017} }

  author = {Yoshizawa, Shigeru and Matsushima, Rie and Watanabe, Mariyo F. and Harada, Ken-ichi and Ichihara, Akira and Carmichael, Wayne W. and Fujiki, Hirota},
  year = {1990},
  title = {Inhibition of protein phosphatases by microcystis and nodularin associated with hepatotoxicity},
  pages = {609--614},
  volume = {116},
 number = {6},
  issn = {0171-5216},
  journal = {Journal of Cancer Research and Clinical Oncology},
  doi = {10.1007/BF01637082},
  • Does that mean you want to use \parencite with square brackets and want to change to round brackets for @online entries? What should happen if you cite two sources in the same \parencite - a @book and an @online, say? Do I get square or round brackets? BTW: Please have a look at how to write a MWE/MWEB. Your MWE runs, but it contains many unneeded packages. Your example also includes no .bib file and example entries. – moewe Jun 19 '17 at 10:01

In that case you can't use the redefinitions you currently use, since we must be able to use round brackets.

Instead put


into your preamble.

This uses round brackets for @online and square brackets for all other types. (You should use @online instead of @misc for online entries, if you must use @misc, replace \ifentrytype{online} by \ifentrytype{misc}).

Note that this will not give good output for \parencite{foo,bar}. But it is unclear what you would want in that case.


\usepackage[backend=biber, style=authoryear]{biblatex}



\parencite{sigfridsson} and \parencite{ctan}


[Sigfridsson und Ryde 1998] and (CTAN 2006)

in the citations.
