This is the third of our conversations on the skills of historical thinking, and this time the subject is sourcing. It’s a term invented by Sam Wineburg–patron saint of this podcast, whom you can listen to in Episode 100, also talking about sourcing–and it refers to the act of identifying sources, contextualizing and assessing documents for bias, reliability, relevance, and point of view. To paraphrase the title of one of Sam's books, sourcing is perhaps the most unnatural act of historical thinking, and it's one that teachers of history perhaps find the most difficult to teach.

That's certainly the case for Leah Shopkow, Professor of History at Indiana University in Bloomington. The difference is that she decided to something about it, not just for herself, but for all those attempting to teach sourcing. This she has done in a new book The Saint and the Count: A Case Study for Reading Like a Historian. It’s an exciting book because it's really what I hope will be a new genre.  Simultaneously it's both a monograph on a medieval subject that should be of interest to any medieval historian, and a primer for undergraduates (and graduates; and even faculty) on the art of historical thinking. This is like finding a delicious candy bar that scares away bears, and helps you lose weight.

(This week's image was suggested by Leah Shopkow; it's of a reliquary designed to contain a relic of St. Thomas Becket, and on its sides shows his murder. When you listen to the podcast you'll realize how appropriate this is.)
