These two volumes form a comprehensive bibliography of published works dealing with the vertebrate paleontology of regions other than continental North America, through the year 1927. Together with two bibliographies by the late Oliver P. Hay dealing with North American vertebrate fossils up to the same date, and the series of volumes by Charles L. Camp and his associates, which give a world-wide coverage from 1928 on, it will provide a coverage of the entire subject from its beginnings to the present. In future publications in the field, considerable valuable journal space (and expense) might be saved by the omission of lengthy bibliographies with, instead, references to the citations contained in this series of bibliographies. In no subject, I think, is there so great a need of knowledge of the antecedent literature as in vertebrate paleontology. Because of the rarity of specimens of many fossil forms, knowledge of all known materials, old and new, is often important for a study of any breadth, whether morphology, stratigraphy, distribution, or systematics be the center of interest. The late Doctor Hay published in 1902 a bibliography and catalogue 1 of works on North American fossil vertebrates to the year 1900; he followed this in 1929 with a second publication 2 covering essentially the next 27 years. Soon thereafter, Dr. Charles L. Camp began, with the collaboration of colleagues at the University of California, the compilation of indexed bibliographies which have for later years covered the entire world literature in rather similar fashion. The late Doctor…

We transliterate these alphabets (Bulgarian, Russian, Serbian, Ukrainian and White Russian) according to the Library of Congress rules of 1931 with a few minor changes such as using i for H, rather than ̄i. Various other commonly encountered transliterations are added in parentheses in the table below. Traditional spellings of some well-known names are retained (e.g., Salensky for Zalenskiǐ).
