The NRAO 91 m transit telescope and rebuilt four-feed receiver were used to make a 1400 MHz continuum survey with 12.7 arcmin x 11.1 arcmin resolution. New maps covering ascension between 19 h 30 m and 7 h 30 m supplement those in the right ascension range between 7 h 30 m and 19 h 30 m (Condon and Broderick, 1985) to complete the roughly 6.8 sr declination band between -5 deg and +82 deg. Both sets of maps are confusion-limited and contain roughly 3000 sources per sr stronger than 0.15 Jy. They are available on FITS tapes and can be displayed and analyzed with standard AIPS programs. A procedure for making radio 'identifications' automatically from the map tapes is given. A 1400 MHz radio sky atlas of contour plots and coordinate-grid overlays covering declination between -5 deg and +82 deg with a roughly 200 arcsec/mm scale was also produced.
