Each collection has a purpose.
The Public Gateway welcomes. The First Foundation establishes an initial literary foundation. The Five Gates extend that foundation; major canonical collections develop the larger body of thought. Reference works clarify language and relationships, while educational materials support study and reflection.
Keep the layers distinct.
A library contains collections. A collection may contain series, works, volumes, chapters, and entries. Titles identify works; edition statements identify textual presentations; registry and archive systems preserve their relationships and history.
The Atlas reference volume
Atlas Reference Volume I — The Sanctum Library explains this architecture. It is a reference companion, separate from the numbered realm volumes. The Living Atlas then explores how wisdom becomes shared culture.
