Access & Usage Guidelines

1. Overview

The 1990 Web Archive is a non-profit digital preservation initiative dedicated to capturing, storing, and providing access to early web content (1990–2005). Our mission balances open access with ethical preservation, copyright compliance, and data integrity.

These guidelines outline access levels, permissible use cases, technical integration methods, and attribution requirements. Violations may result in access suspension or API token revocation.

2. Access Tiers

Access to the archive is structured to balance public education, academic research, and institutional preservation needs.

To upgrade your access tier, submit a request through the Researcher Portal. Approval typically takes 3–5 business days.

3. Usage & Licensing

Content in the 1990 Web Archive is governed by a tiered licensing model based on copyright status, source origin, and preservation ethics.

Permitted Uses

• Academic research, historical analysis, and digital humanities projects
• Non-commercial educational materials and museum exhibitions
• Personal preservation and archival backups (with attribution)
• Algorithmic analysis of early web design, markup, and media formats

Content Warnings

Early web content may contain outdated media formats, broken resource links, or material reflecting historical viewpoints. The archive preserves these artifacts without alteration but may apply content warnings where appropriate.

4. API & Technical Access

The 1990 Web Archive provides a RESTful API for programmatic access to metadata, rendered previews, and archived payloads.

GET /api/v2/snapshots/{id}
Host: api.1990webarchive.org
Authorization: Bearer <YOUR_TOKEN>
X-Access-Tier: researcher

Rate Limiting & Throttling

API endpoints enforce sliding window rate limits. Exceeding thresholds returns 429 Too Many Requests with a Retry-After header. Bulk operations should use the /api/v2/batch endpoint with paginated cursors.

Data Formats

Archived resources are available in multiple formats:

• original: Unmodified HTML/CSS/JS as captured
• normalized: Modernized charset, resolved relative paths, safe sandboxing
• rendered: Base64-encoded screenshot (1920x1080, Netscape 4.0 emulation)

5. Citation Standards

Proper attribution supports archival sustainability and academic integrity. All published works utilizing archive data must include a persistent citation identifier.

1990 Web Archive. (Year Captured). "Title of Archived Page" [Snapshot].
Retrieved from https://archive.1990web.org/snap/{HASH}
Access Tier: {TIER} | Verification: {CHECKSUM}

For journal publications, include the WAC-DOI (Web Archive Citation) prefix followed by the snapshot hash. Example: 10.1990wac.a7f92c

6. Preservation Ethics

Digital preservation requires balancing accessibility with respect for historical context and creator intent.

• Integrity First: Never modify original byte streams. Annotations must be stored separately in _metadata.json.
• Privacy Considerations: Personal contact information, guestbooks, and private directories may be partially redacted in public views per GDPR/Fair Use guidelines.
• Context Preservation: Archived pages are accompanied by capture logs, user-agent strings, and server response headers to preserve technological context.

7. Compliance & Takedown Requests

The 1990 Web Archive complies with applicable copyright laws, including the DMCA and international fair use/dealing provisions. We process legitimate takedown requests within 14 business days.
