The TeX Catalogue Online   Balancing columns at last page.
LaTeX's built-in two-column code finishes off a document exactly
where the text stops; this will typically leave an isolated
left-hand column, or a right-hand column shorter than the left-
hand one. This package modifies the LaTeX output routine to make
the two columns as nearly of the same length as possible.  The
package is part of the sttools bundle.  See also balance.  The
