scientific report two columns

While looking for something on this site I accidentally found a document class which is perfect for a scientific report with two columns layout.

Unfortunately I forgot its name. Could someone point me out the document classes which implements two column layout without using multicol packages?

Article is one such class. \documentclass[twocolumn]{article}. –  Mike Renfro Dec 21 '11 at 17:13

There are some special classes primarily for paper submissions which offer a two-columned text body with easy float placement.

There are probably some more which I don't remember at the moment. And I'm not sure if these classes are good for general use and documents that go beyond a certain number of pages.

All the standard document classes have this - article, book and report. Just add the twocolumn option to the document class. For example, \documentclass[twocolumn]{article}. Here is a minimal example:

\documentclass[twocolumn]{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\begin{document}
\section{Introduction}
\lipsum[1-10]
\end{document}​​​​​​​​​​​​​​​


Although these document classes also support the use \twocolumn, the document option is preferred. For more on mixing columns (for say 1-column abstract in a 2-column document), see the appropriately named UK TeX FAQ entry.
