### ERRATA CORRIGE:

Due to a mistake in the typesetting process of the
present volume, the paper

A. Burstein, S. Kitaev, T. Mansour: *Partially
ordered patterns and their combinatorial interpretations* (27-
-38)

appears erroneously coauthored by T. Mansour.

Here you can find the corrected version of the
paper.

The editor begs the pardon of both the authors and the
readers.
