Cometography is a multi-volume catalog of every comet observed from ancient times up to the 1990s, when the internet took off as a medium of scientific record. It uses the most reliable orbits known to determine the distances from the Earth and Sun at the time of discovery and last observation, as well as the largest and smallest angular distance to the Sun, most northerly and southerly declination, closest distance to the Earth, and other details, to enable the reader to understand each comet's physical appearance. Volume 6, the final volume in the catalog, covers the observations and pertinent calculations for every comet seen between 1983 and 1993. The comets are listed in chronological order, with complete references to publications relating to each comet and physical descriptions of each comet's development throughout its apparition. Cometography is the definitive reference on comets through the ages, for astronomers and historians of science.

This catalog is the first in-depth investigation of comets that were reported since the 17th century, but not confirmed and subsequently lost. Volume I of this two-volume work covers objects observed between 1600 and 1899, a period that was dominated by visual observations and was experiencing a rapid evolution in science.The book uniquely combines the history and culture of comet hunting and discovery with modern tools of orbital mechanics to present a wholesome catalog of unconfirmed and suspected comets. Each case includes a presentation of the observations, a discussion about the observer (when possible), consideration of the historic context, and a conclusion as to the nature of the object. In most cases, the book presents material from original sources, including some never before published that were acquired from observatories, libraries, and historical societies around the world.Although some of these unconfirmed comets turned out to be misidentifications of planets or star clusters, fabrications, or poor observations of comets that were already being observed, the Authors did identify many objects that were likely real comets. In some cases, the Authors were even able to derive orbits for the first time. These observations may be valuable in the future, as they could prove to be observations of periodic comets still to be discovered.

This two-volume catalog is the first in-depth investigation of comets that were reported since the 17th century but not confirmed and subsequently lost. Volume 2 covers objects observed between 1900 and the present, a period that was dominated by photographic observations and the detection of much fainter objects.This book provides a distinctive blend of the historical and cultural aspects of comet hunting and discovery, along with the utilization of contemporary tools in orbital mechanics and data analysis. This comprehensive compilation offers a thorough catalog of unconfirmed comets. Each case encompasses a detailed presentation of observations, a discussion on the observer (when feasible), an examination of the historical context, and a conclusive analysis of the object's nature. The book predominantly showcases original material and photographs sourced from observatories, libraries, and historical societies worldwide; exposing a significant number ofillustrations that have never been previously published. While some of these unconfirmed comets were determined to be misidentifications of minor planets, artifacts caused by emulsion or optical effects, or inaccurate observations of comets that were already under observation, the Authors did manage to identify numerous objects that were likely genuine comets. These observations hold potential value for the future, as they could be observations of periodic comets yet to be formally identified. In a handful of instances, the Authors were also able to find new observations, which led to the calculation of orbits for the first time, enabling a formal announcement, or identifying suspected comets that were already known to be periodic comets.
