Cometography is a multi-volume catalog of every comet observed throughout history; this fourth volume includes a detailed account from 1933 to 1959. It draws from the most reliable orbits known to pinpoint the exact location and path of each comet. The comets are listed in chronological order, and each entry includes details about physical appearance as well as references to publications relating to the comet for further reading. This book is the most complete and comprehensive collection of comet data available, and provides amateur and professional astronomers, and historians of science, with a definitive reference on comets through the ages.
