  We present zBootes, a new z-band photometric imaging campaign of 7.62 square
degrees in the NOAO Deep Wide-Field Survey (NDWFS) Bootes field. In this paper,
all of the images for this survey are released as well as the associated
catalogs. The final zBootes catalogs are complete (at the 50% level) to 22.7
mag over 50% of the field. With these depths, the zBootes images should be
sensitive to L* galaxies to z~1 over much of the survey area. These data have
several possible applications including searching for and characterizing
high-redshift quasars and brown dwarfs and providing added constraints to
photometric redshift determinations of galaxies and active galaxies to moderate
redshift. The zBootes imaging adds photometric data at a new wavelength to the
existing wealth of multi-wavelength observations of the NDWFS Bootes field.
