The Green Bank 4. 85 GHz (λ ~ 6 cm) survey was made with the NRAO seven-beam receiver on the (former) 91 m telescope during 1986 November and 1987 October. The final set of sky maps covering the declination band 0ᵈeg^ = 18 mJy. This catalog is available in machine-readable versions with either B1950 or J2000 positions and as a printed book with B1950 positions. The GB6 weighted differential source counts S⁵/2ⁿ (S) between 18 mJy and 7 Jy agree well with evolutionary models based on independent data.
