The ashcan has the complete text of the adventure with minimal layout. It includes: all the tables, timelines, NPC and location descriptions, intro and endings, plus a couple of less detailed maps. So, everything you need to run the scenario! That said, it doesn't include: 99% of the art, a handful of notes, diagrams, and bits of scripture that provide bonus context, the final polished maps, or the file of printable notes & unlabeled maps to give to players. I do also think the full layout makes the timelines easier to navigate. Hope that helps!
