  The Severi variety $V_{d,n}$ of plane curves of a given degree $d$ and
exactly $n$ nodes admits a map to the Hilbert scheme $\mathbb{P}^{2[n]}$ of
zero-dimensional subschemes of $\mathbb{P}^2$ of degree $n$. This map assigns
to every curve $C\in V_{d,n}$ its nodes. For some $n$, we consider the image
under this map of many known divisors of the Severi variety and its partial
compactification. We compute the divisor classes of such images in
Pic$(\mathbb{P}^{2[n]})$ and provide enumerative numbers of nodal curves. We
also answer directly a question of Diaz-Harris about whether the canonical
class of the Severi variety is effective.
