I'll second the Anatomy of an Epidemic recommendation, it's really quite an amazing book. The comment below by the "pharmacist" is odd in that he hasn't read the book and knows nothing about it even though it is a major work. In particular, it has around 1080 citations in the notes at the end, most of which are to medical journal articles.
