From i-medicine.info, the Diseases Database provides a useful reference service for medical practitioners and researchers. The Database website offers a cross-referenced index and search portal that cover such topical areas as Symptoms and Signs, General Internal Medical Disorders, Drugs and Medications, Congenital and Inherited Disorders, and more. The Diseases Database index is modeled after a standard medical textbook, and "was inspired by the 'surgical sieve' classification and memory technique used as medical school..." The site contains dictionary type definitions for many items via links to the National Library of Medicine's Unified Medical Language System, A 'pre-loaded' multiple search engine inquiry page using all item synonyms, subject specific hyperlinks to web information resources for many items, and more. Links on the site also include: Tips for Searching, Database Content FAQ, Site Troubleshooting Tools, and a Feedback Page. This site is also reviewed in the May 28, 2004 _NSDL Life Sciences Report_.
