Originally published in 1987, Problems and Methods in the History of Medicine is a collection of papers surveying and assessing the particular approaches and techniques which have been used in the history of medicine in the past or are still being developed (from the influence of Annales to the role of the computer). The emphasis is on historical practice rather than methodology in isolation. Besides the topics indicated above, a third problematic is that of historical demography. A common theme to all three groups of paper is the relation between quantitative ‘hard’ data and qualitative ‘soft’ data.
