page-breakingsectioning
Given LaTeX likeso:
\section{Heading}
Here is some text after the heading.
How could one prevent the Heading from showing up at the very bottom of the page?
In other words, how could one prevent a page-break after Heading and before the following text?
This seems to be happening in a document that I've got. If there's more information that would be helpful, I'd be happy to post more of the entire LaTeX document.
Have a look at the needspace package. The functionality also exists in for example memoir. With it you can add something like: \needspace{5\baselineskip} before the headline. If not the given space is left on the page a page break will be inserted and in your case the header will end up on the next page.
Without any additional package, add the following lines in your preamble
\makeatletter
\renewcommand\@afterheading{%
\@nobreaktrue
\everypar{%
\if@nobreak
\@nobreakfalse
\clubpenalty 1
\if@afterindent \else
{\setbox\z@\lastbox}%
\fi
\else
\clubpenalty 1
\everypar{}%
\fi}}
\makeatother
MWE:
\documentclass{book}
\usepackage[showframe]{geometry}% just for this example
\usepackage{lipsum}
\newcommand{\dummy}{This is a test }
\makeatletter
\renewcommand\@afterheading{%
\@nobreaktrue
\everypar{%
\if@nobreak
\@nobreakfalse
\clubpenalty 1
\if@afterindent \else
{\setbox\z@\lastbox}%
\fi
\else
\clubpenalty 1
\everypar{}%
\fi}}
\makeatother
\begin{document}
\lipsum[1-6]
\section{bla}
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test
This is a test
\end{document}

This should rarely happen with the standard document classes (and the better-known ones such as
memoirandkoma). Are you using a homegrown document class or redefining the\sectioncommand yourself?
