Advanced semantic & cross-language discovery
Research across the Knowledge Library
Search across languages and representations while preserving original-language provenance, ranking explanations, record context, working sets, and saved research.
Research pathways
Discover by research task
Discovery
Enter a research question or browse with filters.
Independent primary application
Search the Knowledge Library
Discover publications, source records, datasets, research objects, and connected evidence through the Library API.
Results
Enter a question, topic, title, author, or source to begin.
Historical archives & primary sources
Historical Archives Research Workspace
Search institutional repositories, inspect archival context and derivation lineage, compare primary sources, preserve uncertain dates, and assemble reproducible research packets without treating provenance as truth or authenticity certification.

Primary-Source Comparison & Source Criticism Workspace
Compare archival sources dimension by dimension, preserve provenance and mediation, record human judgments explicitly, and map corroboration or contradiction without converting those observations into truth, reliability, or authenticity scores.

Current source set
Sources to compare
Add at least two sources in the Archives workspace, then return here.
Human-asserted relationships
Relationship observations
Optional JSON array. Relationships remain explicit human assertions and are never treated as truth.
Claim-source ledger
Corroboration & contradiction
Optional JSON array of claims and source observations. Counts are descriptive, not probabilities.
Workspace output
Comparison & criticism
Matrices and corroboration ledgers appear here.
Historical events · uncertain dates · competing chronologies
Research Timeline & Historical Event Workspace
Build source-linked historical event objects, preserve exact and uncertain date ranges, inspect source coverage, and compare competing chronologies without manufacturing false precision or automatically selecting a preferred account.

Archival source context
Available primary sources
Sources are inherited from the current in-browser Archives source set. Their count is descriptive, not a confidence score.
Add sources in the Archives workspace to link them to events.

Working chronology
Historical events
No events added.
Competing chronologies
Compare chronologies
Enter a JSON array of additional chronologies. Cross-chronology alignment occurs only for events sharing an explicit event_key; no fuzzy event merge or winner selection occurs.
Workspace output
Timeline analysis
Timeline, source-coverage, and chronology-comparison output appears here.
Research annotations · scholarly notes · explicit anchors
Research Annotation & Scholarly Notes
Attach interpretive notes, questions, summaries, critique, and methodological observations to explicit research targets and locators without turning annotations into source content, evidence truth, or citations by default.
