Scope & historical calendar dates

The explorer covers 1 January 1939 through 31 December 1945 in the Asia–Pacific theatre: China, Japan, Korea, Southeast Asia, Burma, the Philippines, Pacific islands, Australia/New Guinea and relevant eastern Indian border operations. Fighting in China preceded 1939; this interface’s starting date does not mark the beginning of that conflict.

The selected day is a publication date, taken from the newspaper issue or catalogue metadata. It is not automatically the event date, dispatch date, receipt date or first appearance of a syndicated report. Dates are stored as calendar strings with no invented time of day; UTC is used only for arithmetic and formatting to prevent browser timezone shifts.

“On this date” shows only records published that day. An empty day stays empty. Date-range mode is explicit and includes only publication dates inside the chosen range. After Japan’s formal surrender on 2 September 1945, reporting is labelled surrender follow-up and aftermath. Later fighting, including in Java and Indochina, must be identified as subsequent conflicts rather than an uninterrupted WWII front.

A report establishes what was reported

A contemporary article is evidence of what an outlet printed. Source fidelity means preserving that wording faithfully; it does not mean treating the outlet’s claims as true. Its claims, predictions, scheduled events and figures are not automatically independently verified historical facts. Propaganda, censorship, limited access, delayed dispatches and editorial decisions shaped what readers could see.

Allied-country newspapers, Japanese-controlled occupation press and official military bulletins represent distinct institutions. They are not interchangeable voices. A Tokyo dateline in a Singapore or New Zealand newspaper does not make its publication country Japan. Publication place, historical political context, modern geographic label and editorial control remain separate fields.

Headlines retain historical wording, incomplete titles and possible OCR errors. Offensive terminology may occur within source wording; its preservation does not endorse it. Original OCR, corrected transcriptions and translations are labelled separately. Modern catalogue annotations and summaries are not contemporary article bodies. Political and national perspectives are retained rather than excluded because they contain propaganda. Missing quotations, article bodies and citations are never generated.

Verification is specific to the evidence

Discovery only: an identifiable record awaiting fuller bibliographic confirmation. Archive metadata: issue date, identifier and bibliographic information checked against archive/indexed records. Dataset metadata: checked against supplied archive dataset fields. Catalogue checked: checked against an individual primary catalogue record. Scan checked: an original image was visually inspected as stated in the source; it does not establish a complete proofread transcription.

The supplied newspaper catalogues are primarily discovery and metadata research. Original newspaper page images have not been individually proofread. Some archive pages refused automated access. Two identified Newsmap scans were visually inspected in the supplied research; that limited check is preserved at record level.

Content availability distinguishes full retrieved text, partial fragments, archive-only reading and content not retrieved. Retrieval method, date, record identity match, OCR status and source evidence remain distinct from bibliographic verification and reproduction permission. A downloaded or OCR-extracted body is not automatically scan-verified.

Historical-event links are marked reviewed or tentative. Syndicated duplicates are clustered when evidence supports an association; several reprints are not several independent reports. An unclustered record is not a guarantee of independent reporting.

Why there is no public war map

The supplied research does not contain independently sourced, reviewed wartime control geometry. The public war map is therefore disabled. A modern basemap or an empty map would not provide reliable historical coverage.

The map implementation is retained behind a disabled feature flag for future independently sourced work. It can return only after supported reference dates, validity intervals, precision, reuse rights and evidence review exist. Newspaper claims must never create territorial boundaries or fictional daily fronts.

Metadata access is not article permission

Rights are recorded per record and asset, with separate decisions for metadata, excerpts, full text, images, derivatives and downloadable redistribution. Unknown permissions default to restricted reproduction. The public API and exports enforce those decisions; restricted text is excluded from search snippets and preloaded payloads.

Singapore NLB: the supplied dataset’s Singapore Open Data Licence covers its provided fields and does not automatically clear full scans or whole articles. Third-party material is excluded from that grant. Singapore Open Data Licence.

New Zealand / Papers Past: publisher permissions are conditional CC BY-NC-SA. An established 4.0 or 3.0 New Zealand version is retained exactly; unresolved “New Zealand BY-NC-SA” versions stay unresolved. Attribution, licence notices, modification notices and ShareAlike may apply. Separately owned agency stories, photographs and other contributions need their own assessment. Nonprofit operation alone does not determine noncommercial use. CC BY-NC-SA 4.0 · CC BY-NC-SA 3.0 New Zealand.

U.S. Newsmap: selected individual Truman Library item records state public domain. These are U.S. War Department military publications, not independent civilian newspapers. Their item-level statements are preserved, but no remote scan is fetched or reproduced merely because its catalogue is readable.

Freely readable archive pages and pending-rights records are not automatically reusable article content. Source links open in the archive; live archive pages are not embedded. Required attribution and licence evidence travel with approved assets.

Selected sources, uneven perspectives

The coverage page counts actual published database records by month, outlet, publication country and year. Counts describe catalogue records, not unique events, independent reporters or the total output of an archive. Heavy coverage from one occupation newspaper cannot stand in for all Japanese perspectives; New Zealand newspapers cannot stand in for all Allied, Chinese, Korean, neutral or local voices.

No artificial balance is created when evidence is missing. Country labels describe where the publication appeared, not where every claim originated. Source coverage changes only when real records are imported and published; the interface contains no synthetic historical collection.

Provenance & editorial corrections

Imports preserve original files in protected storage, checksums, source line/table locators, raw rows, validation issues and revision history. An unchanged source import is idempotent. Curated field corrections survive later imports. Imports can be reverted when no later conflicting revisions exist; the audit trail remains.

The protected editorial desk lets authenticated editors preview and commit imports, review rejected or ambiguous rows, correct metadata, review rights, link events, resolve duplicates and publish or unpublish. Historical geometry requires its own evidence review before publication. A correction never silently changes a source scan or upgrades its verification level.

For a correction, record the original archive identifier, the disputed field, supporting evidence and the proposed change with the site’s editor. The research catalogue and original archive remain the starting points for verification.
