This is the largest sample yet compiled of over 6,000 disturbed galaxies: observations of galaxies in collision, galaxies exploding or ejecting material, distorted galaxies, and galaxies in near collision with each other. Volume I contains positions in right ascension and declination, galactic latitude and longitude, and super-galactic latitude and longitude, accurate to 15 arcseconds.

A thought provoking study of the powerful impact of images in guiding astronomers' understanding of galaxies through time.
