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.

Repository discovery
Search historical archives
Search execution occurs only when you submit this form. Results are not automatically imported into the Library.
No archive search has been run.

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.
Loading source-criticism workspace…
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.
Loading historical-event workspace…
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.

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.

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.

Browser-local notes
Browser storage provides local continuity only. It is not authoritative Library persistence.

Normalized notes, notebook composition, and export manifests appear here.
Bibliographic metadata · citation lineage · portable exports
Citation Workspace & Bibliographic Intelligence
Normalize bibliographic records, inspect identifier and metadata completeness, find duplicate candidates, compose research bibliographies, and export portable citation packages without equating citation presence or counts with evidence quality.

Working bibliography
Browser-local citation set
This collection is browser-local and exportable. Existing Python/PostgreSQL citation authority remains the durable citation-edge service; no durable citation is written automatically.

Corpus construction · concordance · frequencies · n-grams · co-occurrence
Corpus & Computational Linguistics Workspace
Assemble or inspect corpora while preserving original-language and derived-representation lineage. Analyze token frequencies, KWIC contexts, n-grams, and co-occurrence without treating counts as meaning, evidence strength, or truth.
Loading computational-linguistics workspace…
Working corpus
Preview text corpus
Preview text is analyzed in-memory only. Persisting a corpus requires an explicit signed handoff to the existing v5.47 corpus authority.
Analysis controls
Computational analysis
When a persisted corpus ID is supplied, analysis uses the existing PostgreSQL corpus. Otherwise it uses the text preview at left.
Workspace output
Corpus analysis
Corpus preview, frequencies, KWIC, n-grams, co-occurrence, and export manifests appear here.
Multilingual names · places · historical toponyms · temporal identity
Entity, Place & Historical Toponym Workspace
Compare multilingual entity names, endonyms, exonyms, transliterations, historical place names, temporal validity windows, and explicit resolution candidates without turning similarity or ranking into identity claims.
Loading entity/place workspace…
Authority preview
Entity and name forms
Paste a non-persistent authority JSON object containing entities. Original names and historical validity windows are preserved.
Resolution query

Entity and toponym analysis
Authority previews, historical toponym timelines, resolution candidates, matrices, decisions, and export manifests appear here.
Evidence matrices · contradictions · convergence · attribution · gaps
Research Synthesis Workspace
Compose sources, claims, citations, annotations, timelines, corpus observations, and entity-resolution outputs into a reproducible synthesis without collapsing disagreement into a single automated answer.

Research frame
Question & scope
Structured inputs
Sources, claims & relationships
Paste JSON arrays. Relationships must explicitly name both claim_id and source_id with a stance such as supports, contradicts, contextualizes, qualifies, neutral, or unknown.

Synthesis object
Synthesis objects, matrices, contradictions, convergence patterns, attribution maps, gaps, and export manifests appear here.
Question framing · hypotheses · evidence needs · tasks · decision points
Research Question & Investigation Workspace
Turn a research question into an explicit investigation plan with subquestions, hypotheses, evidence requirements, source strategy, dependency-aware tasks, decision points, stop conditions, and a risk register—without automatically executing or adjudicating the research.

Claims · evidence · support · contradiction · provenance · dependence
Evidence Matrix & Claim Support Analysis
Analyze explicit claim-to-evidence relationships while preserving contradiction, qualification, provenance, source dependence, and evidentiary gaps. Counts and matrix patterns remain descriptive and never become truth or confidence scores.

Datasets · variables · design · uncertainty · effect sizes · evidence
Dataset Discovery & Statistical Evidence Workspace
Discover datasets from explicit metadata, inspect variables and study context, normalize statistical results, audit uncertainty and analytical assumptions, and hand quantitative evidence into the Evidence Matrix without turning significance or model output into automatic truth or causality.
