"The Medical Encyclopedia Index (English version), developed by the University of Maryland, is part of the Medical Reference section of the university's medically reviewed health content for consumers. The index is available in both English and Spanish, with excellent illustrations. It is divided into seven main categories: Symptoms, Injury, Disease, Surgery, Nutrition, Special Topics, and Poison. Users access items within these categories by clicking on a letter of the alphabet and scrolling down to the desired topic, making navigation and retrieval straightforward. When one selects a topic, the text and illustrations appear on a page that provides an overview. The type of information included in the overview varies, depending on how the topic is categorized. For example, an overview article on a disease covers symptoms, treatment, and prevention, whereas an article on a surgical procedure covers recovery and risks. The overview pages are similar to those provided by other consumer health Web sites such as MedlinePlus (CH, Jul'06, 43-6562), but are not as detailed as MedlinePlus's Medical Encyclopedia (CH, Feb'08, 45-2951). Helpful features on the overview pages are an Ask the Expert form for submitting questions, a video that provides more details about a topic, and related content that includes patient success stories. Two impediments are that the Search feature on the main page was not working at the time of this review, and that the reading level is appropriate only for those at a 10th-grade reading level or above." from Choice, April 2009
