  The Canadian Network for Observational Cosmology (CNOC2) Field Galaxy
Redshift Survey is a spectroscopic/photometric survey of faint galaxies over
1.5 square degrees of sky with a nominal spectroscopic limit of R_c=21.5 mag.
The primary goals of the survey are to investigate the evolution of galaxy
clustering and galaxy populations over the redshift range of approximately 0.1
to 0.6. The survey area contains four widely separated patches on the sky with
a total spectroscopic sample of over 6000 redshifts and a photometric sample of
over 40,000 galaxies with 5-color photometry. We describe the survey and
observational strategies, multi-object spectroscopy mask design procedure, and
data reduction techniques for creating the spectroscopic-photometric catalogs.
We also discuss the derivations of various statistical weights for the redshift
sample which allow it to be used as a complete sample. As the initial release
of the survey data, we present the data set and some statistics for the Patch
CNOC0223+00.
