The \chaptermark and \sectionmark macros store the text of the chapter/sections for the headings, add the numbering (and, if the class defines this, also the chapter label) and passes all that it to \markright and \markboth (in two-sided documents), resp. \markright and \markboth pass its content to the headings. (See scrguien.pdf, sec. 3.6 for \chaptermark and the following for \markright/ \markboth: http://www.giss.nasa.gov/latex/ltx-264.html ) So, \chaptermark calls \markboth or \markright and adds the numbering and label. From book.cls: \def\chaptermark##1{% \markboth {\MakeUppercase{% \ifnum [EMAIL PROTECTED] >[EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] \thechapter. \ % \fi \fi ##1}}{}}% So \chaptermark is more appropriate if you want to modify the heading's text of a real \chapter (where numbering and labelling is needed), while \mark{right|both} is more appropriate for non-numbered headings (if you want the text without any additions in the headings). > On a related note, how does a single chapter, such as the Preface, get > out of sync while everything else has proper running heads?

If you need headings and TOC entries nonetheless, you have to tell LaTeX. Jürgen
