The \Cite command in biblatex capitalises the first prefix in a list of names:

\cite: de Jonge and de Bruin
\Cite: De Jonge and de Bruin

Unfortunately in Dutch publications all prefices need to be capitalised. Basically I need: De Jonge and De Bruin.

This is only valid in the text, in the bibliography I still need "Jonge, M. de and T. de Bruin" (this was achieved with the hack outlined at How can I put a name's prefix in front in citations but *not* in the bibliography?).

Does anyone know how I can fix this in biblatex?

  • I'm surprised regarding your question. As far as I know the Dutch practice is not to capitalize the name prefix unless it is sentence initial.

  • Nope. If the surname has something in front of it, the prefix takes a small letter: Mr. de Bruin Tom de Bruin If it has nothing in front of it, it takes a capital: 'According to De Bruin' 'As quoted in De Bruin and De Jonge.' Feb 9, 2015 at 16:17
  • Well, have a look at the following link: books.google.de/…

    What can I say, that book is wrong. And in some places horribly so, on page 70 there is a sentence beginnen with 'van Fraassen', and sentences always start with capital letters. Here is an English and Dutch explanation. en.wikipedia.org/wiki/Van_(Dutch)#Collation_and_capitalisation onzetaal.nl/taaladvies/advies/… Feb 10, 2015 at 12:46

    Do you really want to argue about this? I shared the rules, that's just how it is. Feb 11, 2015 at 19:07

I just modified the minimal example of lockstep’s answer to your previous question:


\usepackage[useprefix=false,style=authoryear]{biblatex}% "useprefix=false" is the default


  author = {de Author, A. and de Bruin, T.},
  year = {2001},
  title = {Alpha},
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},



  \renewcommand*{\mkbibnameprefix}[1]{\MakeCapital{#1}}}% this is the relevant line of code
  \renewcommand*{\mkbibnameprefix}[1]{#1}}% this sets the name prefix back


Some text \autocite{A01,B02}.

Some text \Autocite{A01,B02}.

    I get the error: "Argument of \MakeCapital has an extra }". Both with the minimal example above and my original document. (and if I ignore the errors it works :D ) Jul 18, 2011 at 15:10
  • @Tom, strange, I don’t get an error. Which version are you using? I have biblatex.sty 2011/05/12 v1.4c

  • v0.9a :D. Updating now. Jul 19, 2011 at 8:44
  • Ok, so after ages trying to update tex, it now works! Thanks! Jul 19, 2011 at 9:47

Perhaps there are better ways to do this:


Now \NLCite has the same syntax as \Cite, but does what you want.
