We present results from a study of the globular cluster (GC) systems of fourspiral and S0 galaxies imaged as part of an ongoing wide-field survey of the GCsystems of giant galaxies. The target galaxies -- the SB0 galaxy NGC1023, theSBb galaxy NGC1055, and an isolated pair comprised of the Sbc galaxy NGC7339and the S0 galaxy NGC7332 -- were observed in BVR filters with the WIYN 3.5-mtelescope and Minimosaic camera. For two of the galaxies, we combined the WIYNimaging with previously-published data from the Hubble Space Telescope and theKeck Observatory to help characterize the GC distribution in the central fewkiloparsecs. We determine the radial distribution (surface density of GCsversus projected radius) of each galaxy's GC system and use it to calculate thetotal number of GCs (N_GC). We find N_GC = 490+/-30, 210+/-40, 175+/-15, and75+/-10 for NGC1023, NGC1055, NGC7332, and NGC7339, respectively. We alsocalculate the GC specific frequency (N_GC normalized by host galaxy luminosityor mass) and find values typical of those of the other spiral and E/S0 galaxiesin the survey. The two lenticular galaxies have sufficient numbers of GCcandidates for us to perform statistical tests for bimodality in the GC colordistributions. We find evidence at a high confidence level (>95%) for twopopulations in the B-R distribution of the GC system of NGC1023. We find weakerevidence for bimodality (>81% confidence) in the GC color distribution ofNGC7332. Finally, we identify eight GC candidates that may be associated withthe Magellanic dwarf galaxy NGC1023A, a satellite of NGC1023.
