This post is a long list of literary landmarks in the United States that I have been maintaining for my own travel and thought the rest of the internet might be interested as I have yet to see a comprehensive site with all this information. I will continue to add to and edit this list as time goes on
Included in the list are places that tie back to an author or book such as a childhood home, statue, or museum.
A * signifies if I have visited the location.
