  Approximately one-third of existing $\gamma$-ray sources identified by the
$\textit{Fermi Gamma-Ray Space Telescope}$ are considered to be unassociated,
with no known counterpart at other frequencies/wavelengths. These sources have
been the subject of intense scrutiny and observational effort during the
observatory's mission lifetime, and here we present a method of leveraging
existing radio catalogs to examine these sources without the need for specific
dedicated observations, which can be costly and complex. Via the inclusion of
many sensitive low-frequency catalogs we specifically target steep spectrum
sources such as pulsars. This work has found steep-spectrum radio sources
contained inside 591 $\textit{Fermi}$ unassociated fields, with at least 21 of
them being notable for having pulsar-like $\gamma$-ray properties as well. We
also identify a number of other fields of interest based on various radio and
$\gamma$-ray selections.
