So I read Providence. Having grown up and living in North Central Massachusetts, I am familiar with many of the locations described in the series. A joke I love to tell (and tell again ad nauseum) is that Providence is nothing but a story about places I've gone drinking. Actually having drunk with people who live on North Orange Road, Athol adds to the detail. But the story seemed complete until I started looking for annotations to describe the plethora of characters and scenes at the end of the book's final chapters. This led me to Neonomicon and Courtyard. Once again, I feel like I have the complete story except for mentions of various Lovecraft written stories.

My first question is now that I have all 18 (2 - Courtyard, 4 - Neonomicon, 12 - Providence), do I have everything?

And my second unrelated question, should I read Jerusalem?

Thank you in advance.
