Here is a reccomendation for those who are always looking to add to your survival library. The book Where There Is No Doctor is a great resource that can be downloaded for free from the Hesperian Foundation here. It is available in English or Spanish. This manual contains information on how to diagnose, treat, and prevent common illnesses and injuries in a user friendly and easy to understand format. It is perfect for those that are looking for a medical reference to use in case there is no access to a health care provider. I would recommend downloading it and printing out a copy for the bookshelf.
