LibreOffice 4.0 Writer Guide - The Document Foundation Wiki

Use page styles (with two columns) for an index or
other document with two columns of text where the
text continues from the left-hand column to the
right-hand column and then to the next page, all in
sequence (also known as snaking columns of text).
If the title of the document (on the first page) is fullpage
width, put it in a single-column section.
For a newsletter with a complex layout, two or
three columns on the page, and some articles that
continue from one page to some place several
pages later, use page styles for basic layout. Place
articles in linked frames and anchor graphics to
fixed positions on the page, if necessary.
For a document with terms and translations to
appear side-by-side in what appear to be columns,
use a table to keep items lined up so you can type
in both “columns”.
