We present results from the Great Observatories Origins Deep Survey (GOODS) on the luminosity function for different galaxy types in the CDF-S. The results are based on observation from both ground based telescopes (ESO 2.2m, NTT and VLT) and ACS on-board HST.

Using the extensive wavelength coverage for this survey (U'UBVRIzJHKs), we estimate photometric redshifts for all galaxies to R_AB~ 26.5 mag. Comparing the photometric redshifts with a training sample of available spectroscopic redshifts, we estimate an accuracy of \sigma_z [(z_spec - z_phot)/(1 + z_spec)] = 0.08 to z ~ 3.

A catalogue based on an R-band (R_AB < 24) selected sample with corresponding photometric redshifts is used to estimate the luminosity function for different spectral types of galaxies to z = 0.5 in U, R and Ks. We also measure the source counts in these bands as a function of spectral type.

Ground-based imaging data were taken at ESO 2.2m, NTT, VLT, and NOAO 4m telescopes and made publicly available.
