We present initial results based on color-selection of high redshift galaxies from the Great Observatories Origins Deep Survey (GOODS). GOODS is collecting extremely deep, multiwavelength data from ground- and space-based facilities, including HST Treasury and SIRTF Legacy observing programs, to enable community research on the distant universe. The GOODS HST Treasury Program is currently imaging two fields, covering ~320 arcmin2, to ``near--HDF'' depths in four bands (BViz) with the Advanced Camera for Surveys (ACS). These data will identify star-forming galaxies out to z~ 6.5, the possible epoch of reionization. We introduce early results on Lyman break selection of high redshift objects from the ACS multi-color imaging. We illustrate the expected colors of high redshift galaxies, selection criteria used to identify Lyman break samples, and some of the properties of objects identified in this way.
Ground-based imaging data were taken at ESO 2.2m, NTT, VLT, and NOAO 4m telescopes and made publicly available.
