We propose to obtain Z-band imaging using the BTC on the CTIO 4m telescope over 20 deg^2 previously imaged in BVI using the BTC in March 1997 as part of a large area survey for z> 5 quasars and other rare objects. Initial quasar candidate selection was performed using object morphology and a (V-I) color criterion. Initial spectroscopy of some brighter candidates in April 1998 revealed that all observed candidates were very late type stars. The addition of Z-band data to the survey will allow us to descriminate between late type stars and high redshift quasars, thereby increasing the survey efficiency significantly as well as allowing issues in galaxy evolution to be addressed with the data set.
