Catchwords: Print first word from next page at bottom of current page

Question

I would like to typeset catchwords. That is, I would like to put a “preview” of the next page’s first word at the bottom of every page.

An example taken from the Wikipedia page linked above:

The next page begins with the word (actually word fragment in this particular case) “dos”, and so that word is typeset flush right just below the text-block.

(How) can this be done with TeX?

You can use the fwlw ("First Word, Last Word") package; a little example using a footer defined with the fancyhdr package:

\documentclass{article}
\usepackage[latin]{babel}
\usepackage[a6paper,footskip=0pt]{geometry}
\usepackage{fwlw}
\usepackage{fancyhdr}
\usepackage[veryoldstyle]{kpfonts}
\usepackage{lipsum}
\fancyhf{}
\fancyfoot[R]{\usebox\NextWordBox}
\renewcommand\headrulewidth{0pt}
\pagestyle{fancy}

\begin{document}

\lipsum[4-60]

\end{document}

An image of the first four pages:

The package gives access to the first word on the current page (\FirstWordBox), the first word on the next page (\NextWordBox), and the last word on the current page (\LastWordBox).

The package also offers a predefined page style NextWordFoot to read ahead to the first word on the next page:

\documentclass{article}
\usepackage[latin]{babel}
\usepackage[a6paper,footskip=0pt]{geometry}
\usepackage{fwlw}
\usepackage[veryoldstyle]{kpfonts}
\usepackage{lipsum}

\pagestyle{NextWordFoot}

\begin{document}

\lipsum[4-60]

\end{document}
