Often, the best work arises from close engagement with a primary source. As you read, you'll think of questions or begin to shape an argument. The hard part is to find a primary source that addresses the broad general area of interest. Here are some strategies for finding primary sources:

"Providing perspectives from both the Vichy government and the resistance movement, this unique collection constitutes the sum of the French press that actually reached Britain during the Occupation of 1940-44.
