Glad to be of help. Some of the information contained within the books are not solid scenarios, instead references to either sources of inspiration, details on figures in the story to craft your own way to insert them, or potentially being addressed in the upcoming books.
Such is the case with "A Pale Horse" which is a book by Agatha Christie, but details in Occultsim reference characters to use to build your own version of it. Same for figures like Preden Mac Blonag, who is mentioned in a blurb on page 108 of Travels which can be used as a tie in for a canvas or the scenario, so they give you his character stats to use him as you please.
I would call most of the book content that isn't rule-based or hard-scenario (story plot) something like "soft" scenarios, in which you get to determine the narrative. Canvases are sort of this way in that they have core world details and relate to the bigger events at large, but are more fluid in their execution.
I crafted my sequence of adventures from the overall impression of the reads, as opposed to just flat using the static stories. I feel that building in these side jaunts or little connections helps affirm the world at large instead of just directly jumping from adventure to adventure. If there is no interlude, then players start to expect the start and end of a "chapter" and I want the lines blurred so they don't know they are in a greater story.
