Abstract in LaTeX format:
A number of erroneous attempts involving $PQ$-trees
in the context of automatic graph drawing algorithms have
been presented in the literature in recent years.
In order to prevent
future research from constructing algorithms with similar errors we
point out some of the major mistakes.

In particular, we examine erroneous usage of the $PQ$-tree data
structure in algorithms for computing maximal planar subgraphs and an
algorithm for testing leveled planarity of leveled directed acyclic
graphs with several sources and sinks.
