I apologize for what must surely be a FAQ.

In book class and with fancyhdr package, I define fancy headers like
this:

...
\pagestyle{fancy}
\fancyhead[LO]{\slshape \leftmark}
...

This does as I expect, but I want to make the chapter titles lower
case. So I tried:

\fancyhead[LO]{\MakeLowercase\slshape\leftmark}
\fancyhead[LO]{\MakeLowercase{\slshape\leftmark}}
\fancyhead[LO]{\nouppercase\slshape\leftmark}

but don't get lower case. How do I do it?

It is actually explained in fancyhdr's documentation (Section 9, "The
scoop on LaTeX’s marks") .

book.cls itself changes chapter marks into uppercase. Redefining
\chaptermark would probably be the easiest.

\nouppercase takes an argument (\slshape here, which is probably not
what you want). Try \slshape\nouppercase{\leftmark} instead. (Untested.)

Yes I'm starting to read it.

Perhaps, but redefining seems intimidating.

Thanks Alain, your suggestion worked nicely. But I'm wondering why you
said \slshape is probably not what I want. Do you mean \itshape is
preferable?

No.

He will say this:
\nouppercase\slshape\leftmark

is in fact:
\nouppercase{\slshape}\leftmark

Would you use \nouppercase on a command changing the shape of the font?

So \nouppercase act on \leftmark.

That's the only way to do it: if you \MakeLowercase (even if it worked),
it would make *all* the title lowercase.

IMHO it was a Really Bad Idea to uppercase the marks in LaTeX by default
(one of the very few areas where LL missed the point).

I snipped the definition of \chaptermark out of book.cls and just
removed the string \MakeUppercase (and got rid of the extra # in both
cases):

\documentclass{book}
\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhead[LO]{\slshape \leftmark}

\makeatletter
\def\chaptermark#1{%
\markboth {{% removed \MakeUppercase
\ifnum \c@secnumdepth >\m@ne
\if@mainmatter
\@chapapp\ \thechapter. \ %
\fi
\fi
#1}}{}}%
\makeatother
\begin{document}
\chapter{Introduction}
Stuff
\clearpage
More stuff
\clearpage
Yet more stuff
\end{document}

[...]

No. I think he meant that \nouppercase REQUIRES a TEXT argument in curly
braces: \nouppercase{\leftmark}, for example. Putting \slshape after it
makes it try to operate on \slshape instead of on \leftmark.
