All students, especially those students who plan to complete all course assignments and activities, are strongly urged to have a medical diagnosis textbook on hand. The recommended textbook is CURRENT Medical Diagnosis and Treatment, 2012 or 2013 edition, by Papadakis, McPhee, and Rabow. If you do not have access to a medical textbook, some free web references that may be useful include the Merck Manual (http://www.merckmanuals.com/professional/index.html), Up To Date Patient Information, Beyond the Basics (http://www.uptodate.com/contents/table-of-contents/patient-information/beyond-the-basics), and the Medecins Sans Frontieres Clinical Guidelines (http://refbooks.msf.org/msf_docs/en/clinical_guide/cg_en.pdf). If you are currently enrolled at a college, university, or other institution with access to online journals and references, you should check with your library to find out whether you have institutional access to any additional references and resources.
