From the original introduction: Over many years the senior author, assisted by other members of the United States Geological Survey, has accumulated many brachiopods from the Ozarkian and Canadian periods. In 1931 the junior author joined in the study of these collections. Before the study was undertaken, about 170 species of brachiopods representing about 24 genera were known. The authors have added 32 genera and have increased the number of species to 319. In addition to the above mentioned specimens a large collection was studied which was made by C.D. Walcott. All regions of Ozarkian and Canadian strata known in North America, except Newfoundland, are represented in the collections.
