David B. Stratton’s Insurance Defense Blog posted an excellent online medical encyclopedia (see the post here). The Standard Edition of Medcyclopaedia™ includes all text and images from The Encyclopaedia of Medical Imaging’s eight book volumes: Physics, Techniques and Procedures, Normal Anatomy, Musculoskeletal and Soft Tissue Imaging, Gastrointestinal and Urogenital Imaging, Chest and Cardiovascular Imaging, Neuroradiology and Head and Neck Imaging, and Paediatric Imaging. The site has an excellent policy about fair use of the text and images.
