  We present results from a study of the globular cluster (GC) systems of four
spiral and S0 galaxies imaged as part of an ongoing wide-field survey of the GC
systems of giant galaxies. The target galaxies -- the SB0 galaxy NGC1023, the
SBb galaxy NGC1055, and an isolated pair comprised of the Sbc galaxy NGC7339
and the S0 galaxy NGC7332 -- were observed in BVR filters with the WIYN 3.5-m
telescope and Minimosaic camera. For two of the galaxies, we combined the WIYN
imaging with previously-published data from the Hubble Space Telescope and the
Keck Observatory to help characterize the GC distribution in the central few
kiloparsecs. We determine the radial distribution (surface density of GCs
versus projected radius) of each galaxy's GC system and use it to calculate the
total number of GCs (N_GC). We find N_GC = 490+/-30, 210+/-40, 175+/-15, and
75+/-10 for NGC1023, NGC1055, NGC7332, and NGC7339, respectively. We also
calculate the GC specific frequency (N_GC normalized by host galaxy luminosity
or mass) and find values typical of those of the other spiral and E/S0 galaxies
in the survey. The two lenticular galaxies have sufficient numbers of GC
candidates for us to perform statistical tests for bimodality in the GC color
distributions. We find evidence at a high confidence level (>95%) for two
populations in the B-R distribution of the GC system of NGC1023. We find weaker
evidence for bimodality (>81% confidence) in the GC color distribution of
NGC7332. Finally, we identify eight GC candidates that may be associated with
the Magellanic dwarf galaxy NGC1023A, a satellite of NGC1023.
