The Castle Rock credits are packed with references to other Stephen King projects. In addition to the map pictured here — which makes note of It's Derry, the Haven crash site in The Tommyknockers, and Little Tall Island from Storm of the Century — are pages from King novels like Needful Things, The Green Mile, and Salem's Lot. The latter is the most important, since it's a snapshot of the vampire book's "Chapter 19." As King fans know, 19 is an important number to the author and has popped up in much of his work, most notably in the Dark Tower series.
