The Atlas of Peculiar Galaxies presents the results of more than four years of direct photography with the 200-inch telescope. Unusual galaxies were selected from lists by Zwicky, Vorontsov-Velyaminov, and unpublished lists by A. G. Wilson, E. Herzog, Wirtanen, the author, and others. Plate files of Mount Wilson and Palomar Observatories were searched for suitable objects, and some of these plates are reproduced. For the most part, however, limiting, good-seeing exposures were obtained on blue-visual sensitive plates at the prime focus (11. 1"/mm) of the 200-inch. The objects are arranged 6 on a page, 57 pages, for a total of 338 objects. Magnifications range from 1X to 10X. They are ordered empirically according to their form and visual appearance, Tabular material presents known data for the objects including positions, plate data, radial velocities when known, references, and remarks on both over-all and detailed peculiarities. The Atlas is also available in large size, 11 x 14-inch photographic reproduction, from the California Institute of Technology Bookstore for a price of about 60 bound.
