BEING ABLE TO REPRODUCE THE PROPERTIES OF MASSIVE GALAXIES IN THE EARLY UNIVERSE IS ONE OF THE GREATEST CHALLENGES TO BOTH SEMI-ANALYTIC MODELS AND HYDRODYNAMIC SIMULATIONS OF GALAXY FORMATION. RECENT OBSERVATIONS UTILIZING STELLAR-MASS-SELECTED SAMPLES (E.G. NEWFIRM MEDIUM-BAND SURVEY ULTRAVISTA) SUGGEST THAT AT HIGH REDSHIFT UV-SELECTED SAMPLES OF LYMAN-BREAK GALAXIES (LBGS) ARE MISSING SIZEABLE NUMBERS OF THE MOST MASSIVE GALAXIES. BECAUSE EVEN THE LARGEST DEEP NEAR-IR FIELD GALAXY SURVEYS CARRIED OUT SO FAR HAVE COVERED AT MOST A FEW DEGREES THEY HAVE ONLY SAMPLED RELATIVELY SMALL VOLUMES OF THE UNIVERSE. THIS MEANS THAT THEY ARE NOT WELL SUITED TO DISCOVERING THE RAREST MOST MASSIVE (M>10^11 MSUN) GALAXIES IN LARGE NUMBERS ESPECIALLY AT HIGH REDSHIFT. AT THE PRESENT TIME WE STILL LACK STATISTICALLY SIGNIFICANT SAMPLES OF HIGH REDSHIFT MASSIVE GALAXIES A NECESSARY FIRST STEP IN UNDERSTANDING THE MECHANISM(S) WHICH DOMINATE STELLAR MASS GROWTH AT DIFFERENT REDSHIFTS AND IN DIFFERENT ENVIRONMENTS. HERE WE PROPOSE TO CREATE MULTI-PASSBAND GROUND-BASED-OPTICAL-THROUGH-HERSCHEL PHOTOMETRIC CATALOGS IN THE FIVE 18 DEG^2 SPITZER SERVS FIELDS WITH THE PRIMARY SCIENCE GOAL OF IDENTIFYING THE LARGEST POSSIBLE SAMPLE OF STELLAR-MASS SELECTED MASSIVE GALAXIES AT 2<Z<6. THESE OBSERVATIONS WILL BE USED TO INFORM THE NEXT GENERATION OF GALAXY EVOLUTION SIMULATIONS ESPECIALLY WITH RESPECT TO THE PHYSICS OF AGN FEEDBACK. BECAUSE SERVS IS THE DEEPEST WIDEFIELD IRAC SURVEY IT SAMPLES PROTOCLUSTER GROUP AND FIELD ENVIRONMENTS WHICH WILL ALLOW US TO UTILIZE THE MULTI-WAVELENGTH CATALOGS TO STUDY NOT ONLY THE RELATIONSHIP BETWEEN STAR FORMATION AND AGN ACTIVITY IN THESE MASSIVE GALAXIES BUT ALSO THEIR DEPENDENCE ON LOCAL ENVIRONMENT. WE EXPECT TO IDENTIFY THOUSANDS OF M>10^11 MSUN GALAXIES AT 3<Z<4 HUNDREDS AT 4<Z<5 AND TENS AT 5<Z<6. OUR ULTIMATE GOAL IS TO ESTABLISH A GOLD SAMPLE OF RARE HIGH-Z MASSIVE SYSTEMS FOR DETAILED STUDY WITH FUTURE MORE POWERFUL TELESCOPES E.G. JWST WITH ITS LIMITED MISSION LIFETIME. ALTHOUGH OFFERING THE DEEPEST WIDEFIELD COMBINED COVERAGE IN THE EXTRAGALACTIC SKY THE SERVS DATASET REMAINS HIGHLY UNDER-UTILIZED. THIS IS PRIMARILY DUE TO THE LACK OF HIGH-QUALITY MULTI-PASSBAND CATALOGS (BECAUSE OF THE COMPLEXITY OF HANDLING OBSERVATIONS FROM MANY DIFFERENT TELESCOPES AND THE DIFFICULTY IN MAKING MERGED MULTI-PASSBAND CATALOGS DUE TO THE LARGE POINT RESPONSE FUNCTIONS (PRFS) AND BLENDING ISSUES OF SPITZER MIPS WISE AND HERSCHEL). BY RELEASING THE CATALOGS PROPOSED HERE ALONG WITH SUPPORTING DOCUMENTATION AND THE CODE USED TO CREATE THEM WE WILL GREATLY INCREASE THE SCIENTIFIC OUTPUT FROM THE SIGNIFICANT RESOURCES ALREADY INVESTED IN THESE FIELDS BY NASA AND CREATE A UNIQUE LEGACY DATASET FOR STUDIES OF GALAXY EVOLUTION FAR BEYOND THE STUDY OF MASSIVE GALAXIES E.G. PROTOCLUSTERS EXTREMELY RED OBJECTS GALAXY CLUSTERING DUST-REDDENED QUASARS STARBURST GALAXIES HOST GALAXIES OF HIGH REDSHIFT SUPERNOVA AND OTHER LUMINOUS TRANSIENT OBJECTS. OUR TEAM IS EXPERIENCED WITH MID- AND FAR-IR SPACE OBSERVATIONS AND HAS A PROVEN TRACK RECORD OF DELIVERING HIGH QUALITY DATA PRODUCTS. THE MULTI-WAVELENGTH PHOTOMETRIC CATALOGS AND CATALOGS OF MASSIVE GALAXY CANDIDATES WE PROPOSE TO CREATE WILL BE MADE PUBLICLY AVAILABLE THROUGH THE NASA-IPAC INFRARED SCIENCE ARCHIVE (IRSA). THE THREE SOUTHERN SERVS FIELDS HAVE BEEN SELECTED BOTH AS DARK ENERGY SURVEY (DES) AND LARGE SYNOPTIC SURVEY TELESCOPE (LSST) DEEP DRILLING FIELDS. OUR TEAM WAS AWARDED 1400 HOURS OF CYCLE 11 SPITZER TIME TO IMAGE AN ADDITIONAL 17 DEG^2 TO SERVS IRAC-DEPTH IN THESE FIELDS AND THREE-QUARTERS OF THESE OBSERVATIONS ARE NOW PUBLICLY AVAILABLE FROM THE SPITZER HERITAGE ARCHIVE. WE ALSO PROPOSE HERE TO COMBINE THESE NEW IRAC OBSERVATIONS WITH DES OPTICAL OBSERVATIONS AS THEY BECOME AVAILABLE PUBLICLY RELEASING OPTICAL-THRU-HERSCHEL DEEPDRILL MULTIPASSBAND CATALOGS ENSURING MAXIMUM LEGACY RETURN.
