My LaTeX document is acting strangely. Here is a simplified version of it:

```
\documentclass{article}

\begin{document}

\tableofcontents
\newpage

\addcontentsline{toc}{part}{A Part of My Document}
\include{includedfile}

\end{document}

```

And in `includedfile.tex`:

```
\section{My Section Title}
Quack.

```

Clearly, in the table of contents, the heading for the part should precede the one for the section, but it doesn't! What's wrong?

Answer: 
Try `\input` instead of `\include` -- it's as if you typed in the contents of the file there. I believe `\include` does some additional processing, so maybe that's causing your problem.
The `\include` macro is intended for inputting chapters in long documents. Thus any file used with `\include` really should start 

```
\chapter{Some-chapter}

```

It also automatically starts a new page (which will confuse the order of things with your `\addcontentlines` instruction, I think). What you want is `\input`. This simply places the contents of the subfile into the TeX source at the current location, with no additional stuff going on. If you replace `\include` with `\input` then all is well. (Note: I'm trying to 'flesh out' the answer given by Reid Priedhorsky here: the end result is of course the same.)
