Re: Lovecraft's America
You want to put Lovecraft's life in the larger context of his times? Excellent question. There are many histories of the USA in the 1920s, prohibition histories, jazz age histories, stock market crash histories, and so on. Histories that focus on New England in general and the state of Rhode Island in particular would serve you best. I would email The Rhode Island Historical Society, which is a library as well as a museum and archive of geneology and public records. Ask them which books cover the period and the place. They'd know. Their website is under their name, rihs . org
Amazon is an endlessly useful resource. I'm not allowed to post links yet but if you search amazon.com under Rhode Island history you'll get many answers.
