"These five volumes on ecology and environment contain 395 original articles by many specialists covering important events of the 20th century, arranged chronologically. Each article follows the same format: basic facts such as category or topic of the event with time and place listed; a brief summary of the event listing key persons involved; a discussion of the event's significance in the history of environmental studies; a bibliography; and cross references. The set contains six indexes: a chronological list of the events discussed; an alphabetical list; a subject/keyword index; a category index; a geographical index; and a list of "principal personages."
