The performance of near-infrared imaging arrays permits photometry and mapping of infrared sources with an efficiency comparable to that provided in the visible by CCD's. An imaging survey of a target list to obtain near-infrared positions, magnitudes and morphology can be pursued at a rate limited by telescope slewing and pointing speed. The Lick Observatory NICMOS array camera was used on an instrument time-available basis to search for any near-infrared counterparts to a sample of unidentified entries in the IRAS Point Source Catalog (PSC). 36 candidates for imaging were selected from 900 unidentified PSC sources (NID=0) within a 30-degree diameter area. Additional criteria used to produce a short list of candidates included flux > 1 Jansky, good flux quality, and 2-band colors similar to those of galaxies, or at least not those of stellar photospheres. Many of the candidates were found to coincide with anonymous galaxies on the Palomar Sky Survey prints. Most of the sources observed are bright in the near-infrared, with J or K magnitudes in the range of 11 to 13.
