- PC-583 personnel during the listed logbook period
- Limitations
- The finding aid verifies the listed logbook span, not the vessel's construction, full service narrative, materials, asbestos content, or individual exposure. It is a discovery aid; the logbooks themselves were not reviewed.

- Finding type
- vessel_history
- Finding
- The live compiled Defoe yard table identifies hull 199 as PC 583, a U.S. Navy sub chaser of 463 tons and 173 feet, delivered 2 September 1942, and reports sale in 1948 as Pan American.

- Population
- Defoe construction workforce, 1942; PC-583 personnel
- Limitations
- This is a compiled historical reference, not a government construction record. It supports working identity and disposition leads only; its builder, dimensions, delivery, and sale statements require primary-record confirmation. It contains no asbestos or material information.

[4]National Archives and Records Administration, 'Researching Asbestos aboard US Naval Vessel up through 1961' [other_primary]
- Locator
- NARA guide, 'Beginning Research' and engineering-drawings/S-code discussion
- Finding type
- asbestos_application
- Finding
- NARA's research guide states that asbestos in U.S. Navy materiel from 1941-61 is a frequent research topic and identifies ship engineering drawings, including S39 Insulation and Lagging and S48 Piping, as records relevant to documenting whether a particular vessel had asbestos material aboard. PC-583's 1942-45 logbook span falls within that research period.

- Study period
- 1941-1961 (guide's stated research period); PC-583 logbooks 1942-1945
- Population
- U.S. Navy materiel research period 1941-1961; PC-583 only as a dated hull within that period
- Limitations
- Program-level research guidance only. NARA expressly frames the listed sources as a starting point for documenting a particular ship; it does not identify PC-583, prove asbestos aboard, identify products or quantities, establish exposure, or establish legal eligibility.

[5]Bowling Green State University Libraries, Special Collections Finding Aids, Defoe Shipbuilding Company (corporate entity 525) [museum_official]
- Locator
- BGSU corporate-entity page: linked resources 'Correspondence between Defoe Shipbuilding Company and the Navy,' 'Shipyard layout and building schedules,' and 'The Defoe Rollover'
- Finding type
- historical_record
- Finding
- BGSU's Defoe Shipbuilding finding aid identifies the company (also Defoe Boat & Motor Works) and lists Navy correspondence concerning launch and completion photographs of naval vessels, shipyard layout and building schedules, and the employee periodical The Defoe Rollover. These are potential construction-era leads for the reported builder of PC-583.

- Study period
- World War II-era holdings; dates not item-reviewed
- Population
- Defoe Shipbuilding workforce and Navy contract records
- Limitations
- The finding aid identifies holdings, not their contents for PC-583. No cited collection item was reviewed and the aid does not establish PC-583 construction details, asbestos use, products, exposure, or disposition.

- Locator
- search_ledger rows sl-uss-pc-583-pc583-01 through sl-uss-pc-583-pc583-06
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, material list, hazmat disclosure, or qualifying asbestos litigation record was located in the completed public sources. CourtListener cannot be counted as a negative finding: its authenticated fleet-pacing limiter stopped the sweep before results were returned and before the remaining base queries could be made.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard PC-583 and does not establish or defeat any exposure or legal claim. This is a limited, documented search result; CourtListener remains incomplete rather than negative.
