  The size, shape and degree of emptiness of void interiors sheds light on the
details of galaxy formation. A particularly interesting question is whether
void interiors are completely empty or contain a dwarf population. However the
nearby voids that are most conducive for dwarf searches have large angular
diameters, on the order of a steradian, making it difficult to redshift-map a
statistically significant portion of their volume to the magnitude limit of
dwarf galaxies. As part of addressing this problem, we investigate here the
usefulness of number counts in establishing the best locations to search inside
nearby (d < 300 Mpc) galaxy voids, utilizing Wolf plots of log(n < m) vs. m as
the basic diagnostic. To illustrate expected signatures, we consider the
signature of three void profiles, "cut out", "built up", and "universal
profile" carved into Monte-Carlo Schechter function models. We then investigate
the signatures of voids in the Millennium Run dark matter simulation and the
Sloan Digital Sky Survey. We find in all of these the evidence for cut-out and
built-up voids is most discernible when the void diameter is similar to the
distance to its center. However the density distribution of the universal
profile that is characteristic of actual voids is essentially undetectable at
any distance. A useful corollary of this finding is that galaxy counts are a
reliable measure of survey completeness and stellar contamination even when
sampling through significant voids.
