Comment: Completely in-universe plot summaries, with no indication of any sort of notability for the grouping.  I already went over above why four of the proposed sources are ineligible for providing any kind of notability, as they are not independent of the series itself.  Having taken a look at the other four, I can now say there isn't enough there to pass .  "Discworld and Disciplines" and "The Intertextuality of Terry Pratchett’s Discworld" are certainly scholarly sources - the problem is they do not really discuss these dimensions at all.  The latter, in fact, is just a text describing the difficulties in translating the series in other languages, and does not mention a single one of these listed dimensions.  That leaves "The Turtle Moves!: Discworld's Story" and "Secrets of The Wee Free Men and Discworld", which ''do'' talk about them somewhat, but only in the context of in-universe plot summary.  There is nothing in them that denotes notability for this grouping
