When we visit my wife's village in Ghana, this is almost the first thing that we pack. Anyone travelling to the less developed parts of the world should take a copy - and leave it there with someone who can use it. This is probably the most widely used medical reference book in the world - it has been translated into 80 languages. Its simple language, clear explanations and illustrations make essential medical knowledge accessible to anyone with basic literacy.

The diagnostic charts are very straightforward and make it easy for a lay person to distinguish between diseases which can be easily confused. The treatments described are completely appropriate for village conditions. There is considerable emphasis on preventative health care and on health education. Anyone familiar with village life in underdeveloped countries will acknowledge that this book is an extraordinary achievement.

For those who complain that it is not relevant to the United States: the book was written for "those who live far from medical centers, in places where there is doctor". However there is plenty of information which *is relevant* to a North American audience, particularly the section on nutrition. Anyone backpacking or camping in the more remote regions of the US would benefit from taking this a long.
