' ... an indispensible references for historians, comet researchers, and true enthusiasts of the field ... the book's value is inestimable and I can only give [it] my highest praise.' John E. Bortle, Sky and Telescope ' ... the first of a series of four, which will provide complete descriptions of every comet that has ever been seen and recorded ... The first volume, which covers comets up to 1799, is a treasure trove of information and each entry stands on its own.' The Journal of the British Astronomical Association 'Cometography has been beautifully produced, and it is a thorough, definitive, well referenced, comprehensive, and easily accessible work of scholarship. For historians, scientific or otherwise, this will be a 'first stop' for information about ancient comets. Looking into the future, it will be a rare month that I will not refer to it, and I am looking forward with eager anticipation to the next three volumes.' David W. Hughes, The Observatory ' ... a very impressive work ... anyone who is engaged in research concerning past apparitions of known comets will find the amount of detailed information in the book extremely useful and potentially significant.'
