Abstract. We examine various issues relevant to localization in the
Anderson model. We show there is more to localization than
exponentially localized states by presenting an example with such
states but where $\langle x(t)^{2}\rangle /t^{2-\delta}$ is unbounded
for any $\delta >0$. We show that the recently discovered instability
of localization under rank one perturbations is only a weak instability.
