Detection and photometry of sources in the U_n, G, R, and K_s bands in a 9x9arcmin^2 region of the sky, centered on the Hubble Deep Field, are described.The data permit construction of complete photometric catalogs to roughlyU_n=25, G=26, R=25.5 and K_s=20 mag, and significant photometric measurementssomewhat fainter. The galaxy number density is 1.3x10^5 deg^{-2} to R=25.0 mag.Galaxy number counts have slopes dlog N/dm=0.42, 0.33, 0.27 and 0.31 in theU_n, G, R and K_s bands, consistent with previous studies and the trend thatfainter galaxies are, on average, bluer. Galaxy catalogs selected in the R andK_s bands are presented, containing 3607 and 488 sources, in field areas of74.8 and 59.4 arcmin^2, to R=25.5 and and K_s=20 mag.
