The sixteenth edition of the Catalogue of Cometary Orbits was issued in 2005. It contained orbits for 3032 comets observed from -239 to 2005, 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/or slight blemishes, but nothing that diminishes the information contained within.
