Catalogue of Cometary Orbits 1972

The first edition of the Catalogue of Cometary Orbits was issued in 1972. It contained orbits for 924 comets observed from -86 to 1972, as well as numerous statistical tables. A limited quantity of the original printing of this catalogue have become available. Complete your astronomical library! The condition is generally excellent: some copies have minor cover fading and slight blemishes, but nothing that diminishes the information contained within.
