What is it?
Personal letters provide unique insight into the convictions and thought of an author and illuminate the context in which that author lived and wrote. The Personal Letters section in the Factbook provides quick access to these texts. For instance, look up Jonathan Edwards in the Factbook, and find every letter within your library written by Edwards.
How does it work?
Open the Factbook and type in the name of an author. Now, you can not only see the works by that author but their personal letters.
