We present current results for AGNs and starburst galaxies in the ISO-IRAS Faint Galaxy Survey (IIFGS). The goal of the survey is to produce a database of Luminous Far-Infrared Galaxies (LFIRG's) at redshifts of about 0.1--1 to help explore the AGN-starburst relationship, study the cosmological evolution of luminous infrared galaxies, and identify possible protogalaxy candidates. The candidate list of ~ 3700 sources has been extracted from the IRAS Faint Source Survey (FSS) using criteria selecting for faint, infrared-bright galaxies. The ISOCAM observations confirm the IRAS detections, yield sensitive 12 mu m fluxes, and provide positions to ~ 10('') accuracy allowing for unambiguous optical identifications. We are obtaining optical magnitudes and accurate redshifts for identified sources with ground-based observations. To date, ~ 420 fields have been observed by ISO and processed with custom software to identify faint point sources. About 85% of the observed fields have an obvious 12 mu counterpart to the FSS source. We have obtained ~ 60 spectroscopic redshifts for the optical galaxies associated with these counterparts, allowing us to derive luminosities and study properties of LFIRG's across a redshift range of z = 0.1--0.7. Topics discussed include global properties of the ISOCAM sample and physical properties of the current spectroscopic subset.
