I've had an interest in medical anthropology for a long time and recently have also become fascinated with what I guess is the history of healthcare. I stumbled on a textbook written in the 1900s for young boys and girls about health, which was great fun to read. Then I was reading Charles Dickens' American Notes and loved his accounts of Laura Bridgman and the various hospitals and institutions he visited. So I'm really interested in reading more texts from throughout history to see how thinking about health developed over time (both physical and mental). Does anyone have good recommendations that I could easily find? I'm mostly interested in primary sources, but if you also have a good scholarly book on the history of healthcare that you'd like to recommend, I would be interested in that too!
One of the best ways to do this is to use Jstor which has digital versions of a wide range of medical journals going back to the 19th century. It also has several journals of medical history for secondary sources. You can read 100 articles a month online for free.
The British Medical Journal has digital archives going back to 1840 [https://www.bmj.com/archive] and is particularly useful for following debates as they developed both in the papers published but also in things like book reviews.
The Wellcome Collection in London has quite a lot of material online [https://wellcomecollection.org]
