We have searched for GCs on CCD images taken with Washington CMT1 filters at the KPNO 0.9m telescope using the following steps: (1) inspection of morphological parameters given by the SExtractor package such as stellarity, full width at half-maximum, and ellipticity; (2) consulting the spectral types and radial velocities obtained from spectra taken with the Hydra spectrograph at the WIYN 3.5m telescope; and (3) visual inspection of the images of each object. We have found 1164 GCs and GC candidates, of which 605 are newly found GCs and GC candidates and 559 are previously known GCs. Among the new objects there are 113 genuine GCs, 258 probable GCs, and 234 possible GCs, according to our classification criteria. Among the known objects there are 383 genuine GCs, 109 probable GCs, and 67 possible GCs. In total there are 496 genuine GCs, 367 probable GCs, and 301 possible GCs. Most of these newly found GCs have T1 magnitudes of 17.5-19.5mag [17.9<V<19.9mag assuming (C-T1)∼1.5], and (C-T1) colors in range 1-2. Description: We obtained Washington C and M and broadband Kron-Cousins R images using the T2KA CCD camera at the KPNO 0.9m telescope on the nights of UT 1996 October 14-25 and UT 1998 October 19. We carried out spectroscopic observation using the Hydra multifiber bench spectrograph and T2KC CCD at the WIYN 3.5m telescope on the nights of UT 2000 September 7-9 and UT 2001 November 2-4.
