Explore the catalog
Browse, search, compare, and explore entries across time, place, measurements, and connections.
Each view explores the same catalog in a different way. Missing dates, locations, or measurements can mean an entry appears in one view but not another.
Most views start with accepted records. The Network also includes proposed records by default. A Proposed label means the record is awaiting review.
Use Filters to narrow the current selection. Available filters depend on the view and data. Selected filters appear above the results, where you can remove them individually or clear the selection.
Kinds are types of entry, such as Person or Building (see kind). All, None, and Reverse selection select every available kind, clear the selection, or reverse it.
Use View as to switch views while carrying the supported selection and focused entry. Some views need data that others do not. A focused entry may remain selected even when it cannot be plotted.
Use the Catalog to browse entries and choose what to explore next.
On the landing page, open a category, select several categories with their checkboxes, or browse all entries. Within a listing:
Date sorting uses the entry's recorded start date. Its meaning depends on the kind: a birth year, completion year, or event date, for example. Entries without a date appear after dated entries.
Favorites is not available in the public demo, even if a filter or bookmarked link refers to it.
Use Timeline to see when things existed or happened, and which periods overlap.
Drag the two handles on the range bar to change the years shown. You can also use the zoom buttons, scroll over the timeline, or select two years on the timeline to set a range. The range handles support keyboard movement when focused.
Use Order to change the date ordering and Layout to switch between horizontal and vertical arrangements. Additional date modes may appear for the selected records, such as Lifespan and Time served for people.
Select an entry once to focus on it. Select it again to open its page. When a row or group has more entries than fit, it says how many aren't shown. Use Show 10 more or Show all to expand it, and Collapse to return.
Entries need a start year to appear. BCE dates are supported. Approximate dates still occupy a position on the chart, so check the entry's date text before interpreting that position as exact.
Use Map to explore the locations recorded for entries.
Drag to move around and use + and − to zoom. Mouse-wheel scrolling does not zoom this map.
Select a pin to focus on an entry and open its popup. Select the popup's name to open the entry page. Use Limit to view to count only the entries inside the visible map area.
Where supported, Arrows connects dated locations in chronological order. These arrows show sequence, not a documented travel route or a causal connection.
Each entry has one stored location point. Its meaning depends on the record: a building's site, for example. A person's point should not be assumed to represent every place they lived or worked.
Use Scatter to compare two numerical fields and look for patterns or unusual entries.
Choose the X and Y axes. Shared fields such as start year, end year, span, and Connections work across multiple kinds. Kind-specific measurements depend on your selection and the available data. Connections means the number of recorded connections an entry has.
Only entries with values for both selected axes are plotted. The page reports how many are shown and which data is missing.
To measure a difference:
Use the entry links in the ruler to open a record. Selecting a point controls the ruler rather than opening the entry.
Under Layout, Two plots shows two plots side by side and One plot returns to a single plot. The two plots' rulers are linked so you can examine the selected entries across both.
Use Network to explore recorded connections. Entries appear as points and connections as lines. The legend identifies connection labels. Line direction and styling help distinguish directional connections from symmetric ones.
The Groups control lets you view all connected groups or focus on one. Main web identifies the main connected group. A group is based on recorded links, not a manually chosen topic.
Use filters to limit the kinds and connection types shown. Where available, Show nearby entries faded keeps surrounding entries visible as context.
The layouts emphasize different aspects of the same records:
Hover over an entry to highlight its links. Select it once to focus on it and again to open its connection map. Scroll to zoom; drag to move around. The zoom and fit buttons offer the same basic controls.
An entry missing from a group may have no recorded connection to it. The absence of a path does not establish that the real-world subjects are unrelated.
The chosen entry sits in the center, surrounded by its connections.
Use Compare to read two or more entries side by side. Select the Compare button (⇄) on catalog cards, then choose Open compare from the tray.
The same rows appear across the columns. A ◆ marks a comparable field. Missing values remain missing; a blank cell is not zero. Follow source badges to check the evidence and pay attention to units.
The tray retains selections as you navigate within the site. Clear selection removes them; reloading resets the tray. Opening an entry's Compare with… link alone gives you one entry, so you still need another for a comparison.
Search matches entry names and descriptions, including partial names. Results are ranked by relevance. Use a more specific name or adjust filters if you don't find what you need.
The sidebar search starts a catalog search. Search within a listing can retain that listing's context. Check the active filters when results look unexpectedly narrow.
Network name lookup is different: it opens the matching entry's connection map, favoring an exact name when available.
Stories are guided readings of catalog records. Open one and scroll to see the accompanying diagram highlight the entries and connections discussed.
Numbered citations lead to the sources. Entries in this story links to the underlying records. Each story identifies whether it was written by a person or drafted with AI.
An entry page brings together its facts, classifications, connections, and external links. Smaller Timeline, Map, or Scatter panels appear where the record has suitable data.
The Links and sources panel separates external identity records (Anchors), further reading (Read more), and Sources. Related suggests entries through shared classifications or connections and explains the match. These suggestions do not create new catalog connections.
Personal notes, tags, collections, and favorites are unavailable in the public demo. For other limits, see Limitations.
