The illustrated dictionary would provide descriptions of commonly used terms in toxicologic pathology accompanied by select pictures and illustrations to augment the written material where appropriate. It would also contain concise but less detailed information, describing the terms used in related areas such as anatomy, metabolism, drug development, and the allied fields of general toxicology. Illustrations would be provided to add visual context to the terms and descriptions. The definitions and descriptions would be prepared and peer reviewed by editors and contributors who are known experts in toxicologic pathology, toxicology, and drug development.
