# How do I install two fonts into a document?

I want to install two fonts tgchorus and fouriernc into a document. The font tgchorus for content of chapters, section, subsection and fouriernc for remain. I don't know to install. How must I do?

You don't really "install" fonts into a document. You just need to use font selection commands when you define your sectioning commands. See How do I use a particular font for a small section of my document on font selection commands. For changing fonts in section headings etc. see How to set the font for \section title (and chapter etc.). –  Alan Munn Dec 28 '12 at 4:40
While the question is interesting by itself, I recommend you not to use Zapf Chancery or any clone thereof for any purpose other than typesetting an invitation or something similar. –  egreg Dec 28 '12 at 23:27

You can try the following.

\documentclass[11pt]{book}
\usepackage[english]{babel}
\usepackage{lipsum}
%%
\usepackage{titlesec}
\titleformat{\chapter}[display]
{\fontfamily{qzc}\selectfont\Huge}
{\chaptertitlename\ \thechapter:}{0pt}{\huge}
%
\usepackage{fouriernc}
\pagestyle{empty}
\begin{document}

\chapter{These Real Numbers}
\lipsum[1-2]

\end{document}


\fontfamily{qzc}\selectfont chooses "TeX Gyre Chorus" without loading \usepackage{tgchorus}.

But you'll get all sorts of values about the size of the font being requested. I'm not sure you can overcome that.

I don't understand, before I could do, but now, I can not do. I receive the massage not find font qzt. –  minthao_2011 Jun 7 at 23:57
