# Retaining chapter page headers with chapter*{}

My question is essentially a duplicate of this but for the book class (for which the solution does not work), namely:

• If I have an un-numbered front-matter chapter (i.e. \chapter*{A chapter}), how can I set the correct chaptermark as if it were a numbered chapter?

Here's a MWE where chapter 2 still has chapter 1's chaptermark:

\documentclass[a4paper,twoside]{book}

\usepackage{arsclassica} % optional
\usepackage{lipsum}

\begin{document}

\chapter{Chap1}
\lipsum

\chapter*{Chap2}
\lipsum

\end{document}


I think possibly the answer is contained in the comment thread under an SO answer, but it's a bit cryptic, suggesting "Try adding \chaptermark{#1} resp. \leftmark / \rightmark.".

(Aside: I'm using the arsclassica package so ideally don't want to overwrite the current chaptermark style.)

• you can insert \markboth{Chap2} after the \chapter* line. – barbara beeton Sep 1 '15 at 14:13
• \markboth{Chap2}{Chap2} fixed the chaptermark text but also changes the style – blmoore Sep 1 '15 at 14:56
• arsclassica is based on scrreport, part of the koma collection, so i have added that identifier to the tags. it's my opinion that the failure to handle running heads properly for starred chapters is a design flaw; as such, it might profitably be brought to the attention of the arsclassica developer, whose address is included in the (very nice) documentation. – barbara beeton Sep 1 '15 at 16:24
• What's the problem in having the chapter after \frontmatter and before \mainmatter? Anyway, I'm not sure that arsclassica should be used with book, but rather with scrbook. It's different with classicthesis that purports to support both classes. – egreg Sep 1 '15 at 16:28

As egreg pointed out, the solution was to just use \chapter throughout \frontmatter.
Where arsclassica was failing to give the correctedly-formatted chapter marks for (e.g.) \listoftables, \tableofcontents etc., I instead used:
\chapter{Contents}
