- PDF p. 116 (PDF page numbering; indexed text line for YMS-197)
- Finding type
- historical_record
- Finding
- National Archives Special List 44, by ship numbers, lists Navy deck-log coverage for YMS-197 from 1943-05-07 through 1945-06-30. These dates describe the listed log coverage only.

- Study period
- 1943-05-07 to 1945-06-30
- Limitations
- This finding establishes the cataloged availability/coverage dates for deck logs. It does not establish commissioning, decommissioning, service events, asbestos materials, exposure, or the logs' contents; the underlying log volumes were not reviewed.

[3]NavSource Online, Mine Warfare Vessel Photo Archive, YMS-197 [other_primary]
- Locator
- Individual hull page, lines 13-29 (identity and history/specifications)
- Finding type
- vessel_history
- Finding
- The individual NavSource page identifies YMS-197 as a YMS-1-class auxiliary motor minesweeper. It is used only as secondary corroboration of hull identity and type; no other history particulars from that page are carried into this record.

- Accessed
- 2026-10-04
- Study period
- 1942-1948
- Limitations
- NavSource is a secondary naval-history archive, not a primary record. The prompt identifies it as corroboration of hull identity; its other particulars have not been independently matched to a primary source and remain provisional. No listed specification supports an asbestos inference or establishes asbestos aboard.

[4]Research search ledger: NHHC/DANFS and Naval Vessel Register searches for USS YMS-197 and YMS-197; no matching hull record located [other_primary]
- Locator
- See search_ledger entries SL-02 and SL-03
- Finding type
- historical_record
- Finding
- A targeted search of primary-source Navy history and registry sources did not locate a matching hull record or documented designation alias for YMS-197. This is a bounded negative search result, not proof that no such records exist.

- Limitations
- Searches were targeted and limited to the named repositories and designations. This does not prove that no Navy records exist, and it establishes nothing about asbestos presence or absence.

[5]Research search ledger for NHHC/DANFS, Naval Vessel Register, and National Archives catalog/logbook sources; bounded search only [other_primary]
- Locator
- See search_ledger entries SL-01 to SL-04
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos documentation was located in the primary hull/history sources searched for this record. The ship's asbestos status is unknown.
- Verification
- partial
- Role
- negative_finding
- Documentation level
- ship_specific
- Accessed
- 2026-10-04
- Limitations
- A failure to locate public documentation does not show that asbestos was absent. The underlying deck logs were not reviewed and the search did not inspect inaccessible or non-digitized holdings, maintenance files, surveys, or individual exposure records. No class- or era-based asbestos inference is made.
