Pueblo Bonito was originally published in 1920, twenty-five years after the Hyde Exploring Expedition first began work at the site in 1896. The re-issue of this volume, long out-of-print and difficult and expensive to obtain, marks the 1OOth anniversary of the onset of the excavation of Pueblo Bonito. The book is a most welcome addition to the list of historically important works on American archaeology and anthropology that have been reprinted during the last several decades. The University of New Mexico Press is to be com­ mended for undertaking to republish this report, especially at such a reasonable price for the paperback.
