Our observations cover an area of ∼5'x5' in the NGC 1333-S region at J-, H-, and Ks-bands. The 10σ limiting magnitudes exceed 18mag in all three bands. Based on NIR color-color diagrams, embedded YSO candidates were identified using NIR excesses. Description: JHKs imaging observations of the star-forming core in NGC 1333 were conducted during the period from 1997 September 22-October 1 using the facility infrared array camera (OASIS) mounted on the 1.88m telescope of the Okayama Astronomical Observatory (OAO) in Japan. The region in common with the OASIS survey was imaged in the JHKs-bands with the Simultaneous-Color InfraRed Imager for Unbiased Survey (SIRIUS) on the 2.2m University of Hawaii telescope on Mauna Kea, Hawaii, on the night of 2000 August 15.

Note (1): 'd' indicates sources saturated in this survey. The values are substituted with Aspin et al., 1994A&AS..106..165A Note (2): For Class II objects, the J luminosity is corrected for the extinction and translated using the distance modulus. Note (3): Our source classification flag as follows: 1 = source classified as Class I object candidate 2 = source classified as Class II object candidate 3 = source classified as Class III object and field star candidate 4 = sources lying below the CTTS locus and to the right of reddening lines Note (4): Sources previously identified in the NIR survey by Aspin et al., 1994A&AS..106..165A
