Charles H. Smith has endeavored in this bibliographic review to include literature bearing on both the biological study of diversity itself, and the socio-natural science of diversity conservation. Two bibliographies are included in this work. Bibliography I lists the approximately 1200 monographs and 4500 shorter articles featured here, whereas Bibliography II provides a selective accounting of special issues of serial publications whose main theme is biodiversity studies-related. Entries are enhanced, as applicable, with bibliometric ratings, key words, and brief annotations. Coverage centers on the period 1986 to 1998, but extends to many works published prior to that date that remain relevant to trends occurring during it. There are three indexes, covering general, geographical, and organismal subjects, respectively, and generating in sum over 20,000 referrals to the items in the bibliography. The work also surveys closely related topics from such allied fields as environmental ethics, nature philosophy, environmental law, agricultural ecology, evolutionary biology, biometrics, sustainable development, environmental policy, forestry, genetics, education, climatology, and paleobiology. While Biodiversity Studies: A Bibliographic Review, is highly recommended for scientists, educators and professionals-to-be, it cites a fair amount of material that can be understood by undergraduates or even high school students.
