The Conversation
The Conversation recently published a summary of Campbell’s work, helping to spread his theories and ideas.
It gives the full scope of his work, ranging from his earliest writings, to adaptions that were made after his death, such as Vogler’s The Writer’s Journey, which serves as Hollywood’s Hero’s Journey.
If you want to re-familiarize yourself with some Campbell, or if you want to learn for the first time, this is a great place to start.
