Origins
Manhattan Engineer District
Historical MED correspondence, contracts, technical reports, procurement records, administrative files, and related public records.
Declassified Document Reading Room
Read the records behind the history.
A curated public reading room for historical nuclear-weapons records whose public availability and release status can be documented. Rosetta preserves provenance, context, citation, and the distinction between what a document establishes and what remains unresolved.

Reading-room collections
Enter through the record.
The foundation establishes permanent shelves now. Documents will be added only after source identity, provenance, public availability, citation, and presentation have been reviewed.
Atomic Energy Commission
AEC Records
Publicly released technical, administrative, production, health-physics, inspection, and program records from the AEC era.
Transition
ERDA & DOE Records
Records documenting the transition to ERDA and DOE, including operations, safeguards, environmental, occupational, and historical materials.
Laboratories
Weapons Laboratories & Facilities
Curated records from laboratories, production plants, test sites, contractors, and other facilities represented in Rosetta.

Contracts, Procurement & Shipments
Records that document contractual relationships, purchasing, accountability, transfers, shipping, receiving, and material movement.
Explore contracts →Events
Occurrences & Investigations
Occurrence reports, investigations, memoranda, corrective-action records, and other public documentation of historical events.

Declassified Technical Reports
Historical technical reports whose declassification or public-release status can be supported by the record itself or an authoritative repository.
A necessary distinction
Publicly available does not always mean formally declassified.
Rosetta will use declassified only when that status is supported. Other records may be described more precisely as publicly released, publicly accessible, unclassified, redacted, or available through an archival repository.
Classification markings, declassification stamps, redactions, distribution restrictions, later release actions, and repository metadata are part of a document's history and should be preserved rather than flattened into a generic label.

What Rosetta will preserve
Document title · creator · date · document number · original classification marking where historically relevant · release/declassification status · repository · collection/accession/SRDB identifier · page citation · public source link · related Rosetta subjects and evidence records.
A document's presence in the Reading Room does not mean Rosetta endorses every statement it contains. Documents are historical sources to be evaluated in context.
Publication discipline
Source first. Context always.
Before a document enters the Reading Room
Rosetta verifies the document identity, source or repository, public accessibility, citation information, and any release-status characterization used on the site. Copyright or repository restrictions are respected.
Foundation Edition
The shelves are established; population follows.
This page establishes the permanent architecture for curated primary-source collections. It is intentionally not filled with unreviewed documents from the private Master Evidence system.
Documents will enter through the same publication-review discipline used elsewhere in THE ROSETTA WEB™.
