The eighth edition of the Catalogue of Cometary Orbits was issued in 1993. It contained orbits for 1392 comets observed from -239 to 1993, as well as numerous statistical tables. This was the first edition that was prepared entirely using TeX. 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.
