The eight book diseases set covers a range of different diseases from sore throats, to the plague to mental disorders. Each book has an index that covers all topics and clearly states the page and volume where information can be found. Articles are clearly organized and are approximately one page in length in language that is accessible for high school students. As this is a reference, information is not in depth but interesting facts are included such as the incidence of ADHD. This provides a great starting point for students beginning research on diseases or to get quick information about these disorders for personal interest. Recommended for use in high school or public libraries. ( )
