The dossier layer gives stable pages for historically important objects: cases, publications, resources, people, organizations, events, and other entities that can be reached from more than one view.
The Timeline is one view over these records. Search, Notebook concepts, Claims Index pages, bibliography pages, and future evidence dockets can also link to the same dossier records without making chronology the owner of the object.
The current TalkOrigins timeline starts with cases, publications, and resources that provide useful entry points into Archive material.
