[latex] Latex Remove Spaces Between Items in List

It's easier with the enumitem package:

\documentclass{article}
\usepackage{enumitem}
\begin{document}
Less space:
\begin{itemize}[noitemsep]
  \item foo
  \item bar
  \item baz
\end{itemize}

Even more compact:
\begin{itemize}[noitemsep,nolistsep]
  \item foo
  \item bar
  \item baz
\end{itemize}
\end{document}

example

The enumitem package provides a lot of features to customize bullets, numbering and lengths.

The paralist package provides very compact lists: compactitem, compactenum and even lists within paragraphs like inparaenum and inparaitem.
