Citation & Source Tiers

Aevum Encyclopedia is built on a foundation of verifiable knowledge. Every assertion, data point, and historical claim is anchored to a traceable source. To maintain consistency and academic integrity, we classify all references into four distinct Source Tiers, each with specific verification protocols, citation standards, and editorial oversight.

The Source Tier System

Our tiered classification ensures readers can instantly gauge the evidentiary weight of any reference. Tiers are dynamically assigned by our AI verification engine and validated by human subject-matter experts.

Tier 1

Primary & Peer-Reviewed

Direct evidence, original research, and academically vetted publications.

Examples: Peer-reviewed journals, government datasets, court rulings, archaeological findings, official statistical yearbooks, patent filings.

Tier 2

Secondary & Authoritative

Expert synthesis, institutional reports, and widely recognized publications.

Examples: Academic monographs, WHO/UN reports, major news agencies (Reuters, AP), university press publications, recognized NGO white papers.

Tier 3

Tertiary & Educational

Curated educational materials and vetted reference works.

Examples: University course textbooks, MOOC materials, reputable dictionaries, historical archives with institutional backing, translated authoritative texts.

Tier 4

Community & Emerging

Contributed insights, preprints, and niche databases requiring review.

Examples: Academic preprints (arXiv, SSRN), expert interviews, field notes, regional oral histories, newly submitted research under verification.

Citation Standards & Formatting

All citations follow a hybrid Chicago-Academic/MLA format, optimized for digital readability and machine parsing. Each reference includes:

Persistent Identifiers: DOI, ARK, Handle, or ISSN wherever applicable.
Access Metadata: Retrieval date, URL stability status, and archive mirrors (Internet Archive, Portico).
Version Tracking: Article snapshots are version-controlled. Citations link to the exact revision used.
Machine-Readable Structured Data: Every citation exports to JSON-LD and BibTeX for seamless academic integration.

Example Citation Output Kim, R., & Okonkwo, L. (2023). Quantum Error Correction in Topological Systems. Nature Physics, 19(4), 214–229.
DOI: https://doi.org/10.1038/s41567-023-01892-4

AI-Assisted Verification Pipeline

Before any source is attached to an article, it passes through our multi-stage verification architecture:

Link & Domain Validation: Automated checks for URL stability, domain authority, and paywall accessibility.
Content Cross-Referencing: AI maps claims against Tier 1 databases to detect contradictions or misrepresentations.
Bias & Context Detection: NLP models flag ideological framing, outdated methodologies, or retracted studies.
Human Expert Review: Domain specialists approve final citation placement and tier classification.

🔍 Transparency Note

If a Tier 4 source is used, it will always be paired with at least one Tier 2 or higher reference. Standalone Tier 4 claims are flagged for community verification and carry a "Under Review" badge until corroborated.

Contribution & Citation Guidelines

Contributors are required to attach sources inline using our standardized markup. Unverifiable claims are automatically quarantined by the platform until references are provided. You can view the complete Contribution Guide or download our Citation Exporter Tool.
