Start with a search
A magnifying glass draws a stream of archive material into distinct subjects: a person, a place, an organisation and an idea.
Search by name and filter by category. Open the entry you mean, then read its recorded facts and the relationships that lead to other entries.

Read a structured record
An amphora sits at the centre of linked circles for places, time, people, books and related objects. An empty outline represents a missing fact.
Open an entity record with its dates, places and identifiers together. Year-only, month-level and full dates stay distinct, and unrecorded facts remain visible as gaps.
A clear route through the information
Let the record guide the next question.

Review dates with their precision, places, coordinates and identifiers. Keep any not-recorded facts in view.
Follow related entries, browse a category or open On this day. Read how one subject connects to another.
Compare key facts side by side. Read the data version, dates and qualifiers, and open a Wikipedia article link where one exists.

Follow explicit relationships
The illustration connects a central sculpture with artists, artworks, books, architecture and places. Each link represents a route to another subject.
Follow the related entries recorded in the data. Explore their fact pages or compare entries side by side, keeping the relationship and recorded details in view.

Documents, film, archives and maps feed a visual source trail. The final panel retains an uncertainty marker alongside the other material.
