I have formatted Chapter titles using the package titlesec, but the formatting is unsuccessful in applying to my chapters with an asterisk *, (those chapters which I do not want appearing in my table of contents.)

That is, I would like to center and make \huge a title which corresponds to \chapter*{Some Title}.

For all my other chapters, I have successfully used:

{\normalfont\huge\bfseries}{\centering\chaptertitlename\ \thechapter}{20pt}{\huge}

How may I do this for \chapter*{}, using titlesec or otherwise?

This is under \documentclass{report}.





{\normalfont\huge\bfseries}{\centering\chaptertitlename\ \thechapter}{20pt}{\huge}


\addcontentsline{toc}{chapter}{Unnumbered Title}
\chapter*{Unnumbered Title}
I would like the title above centered

\chapter{Numbered Title}
...centered like this chapter heading above


Thank you!

    Welcome. Please give us a small, compilable document which reproduces the issue. By default \titleformat affects starred as well as unstarred commands. When I try your format command, the title of unstarred chapters i not centred - only the 'Chapter X` bit which is, of course, not relevant for starred chapters.

You can have what you want with the numberless key. I'm not sure whether you want unnumbered chapters to be in the table of contents; the below code does it, but it's easy to undo it if you don't want. Just use:

\titleformat{\chapter}[display] {\normalfont\huge\bfseries\filcenter}{\chaptertitlename\ \thechapter}{20pt}{}
\titleformat{name=\chapter,numberless}[block] {\normalfont\huge\filcenter\bfseries}{}{0pt}{\huge}[\addcontentsline{toc}{chapter}{\chaptertitle}]
  • (+1) Just for being able to find it. Why doesn't the documentation mention that there are extensions on page 4 when explaining \titleformat as part of the 'Advanced Interface' description. Is that for the 'Very Advanced Interface'? The documentation is... leaves something to be desired.

    It's described in §3.8, Extended settings. Perhaps it's because the author, a little further, ‘discourages using starred versions of sectioning commands’ in favour of ‘mark-up oriented commands’ (§ 4.2) with examples.

  • Thanks. I found it, actually. But I only found it by searching for the option having seen your solution. I just find the documentation frustrating that different features of the same command are explained in a bunch of different places without even a pointer to those other places.

  • @cfr: You're probably right. I guess I don't have this problem only because I've been using the package for more than 15 years. I remember I had difficulties with titletoc.

    Making me think of Groucho Marx's sentence: ‘I don’t want to belong to any club that would accept me as one of its members.’
