View source for In-Universe

“In-Universe” books and other artefacts are ones which present themselves as though they exist within the fictional universe they are part of. That is, Nanny Ogg’s Cookbook is a book in Roundworld, written by Terry Pratchett, Stephen Briggs and Tina Hannan, as though it was written by Nanny Ogg and published in Ankh-Morpork. There are many such books and other artefacts for the Discworld.

== Mapps ==
The first in-universe artefacts were the various Discworld Maps, or “Mapps” as they insist on spelling it.

== Diaries ==
Though they present dates usable in Roundworld, these diaries are all written as though published on Discworld for the benefit of various students and employees. While very much out of print, their fictional content has been collected in {{AMAV1}} and {{AMAV2}}.
