Since last assessment

18 October 2026 to 1 November 2026

Our reading: Since 18 October 2026, 14 emails are on file: 7 sent, 7 received (3 with content, 4 automatic acknowledgements). The response status is unchanged: “Replied, nothing disclosed”. Most material: 29 October 2026, received, not held (ref FOI/2026/09): NLW confirmed that no further classmarks relating to Great House Farm / Tŷ Mawr / Llandough, the 1877 agreement, the 1916 tenancy or the 1938–39 sale have been identified since the July 2026 searches. Next date on file: 13 November 2026. Nothing here changes the earlier current finding unless stated above; this is a log of contact, not a finding about any person.

Page ID: 1562 · Title: National Library of Wales — Forensic Assessment · Evidence status: Not yet labelled — see the Editing Protocol · Version: 1.0.0 · Editing Protocol

Chronology and catalogue links — assessed 10-10-2026: See the Institutional Involvement Roadmap (1877–2026) for the date-ordered institution, people and evidence sequence. The reported 1988 Cadw-to-Minister spot-listing letter has its own placeholder at GHF-E152; the original has not been attached to that page as at 10-10-2026. A placeholder records an evidence gap, not the letter’s content or proof of misconduct.

Forensic Assessment — National Library of Wales

Scope: NLW as archive/custodian, especially the Bute Estate material relevant to the historic title and tenancy chain.

Why NLW matters

The Bute Estate collection is one of the principal remaining routes to the pre-WGR history, including the 1877/early transaction material, Llandough manorial leases and agreements and related estate papers. The project has identified D219 as a priority series.

Forensic control test

Search the catalogue and related uncatalogued material for Great House/Tŷ Mawr/Cedfin, Daniel Thomas, Williams, Llandough and the relevant Bute estate solicitors. Distinguish original deeds, abstracts, rentals, drafts and later copies.

Current finding

As at 10-10-2026, the material reviewed does not establish wrongdoing by the National Library of Wales. This is limited to the archive/search trail identified here and does not rule out further relevant records. The institution is an evidence source and custodian. Missing material must be accompanied by a documented search/retention explanation before any inference is drawn. 🕒

Human action

Arrange a targeted research visit/request for D219 and any Corbett family papers relevant to the 1877 transaction and later land administration. Capture exact classmarks and plan references.

Acceptance: targeted search completed and all relevant classmarks, images or negative-search explanations recorded.

Institutional appearance timeline — linked source index

Coverage rule: this is a chronological navigation map of published Wiki source pages found by searching the current site index for “National Library of Wales”. Every event label links directly to the page containing the source. It avoids duplicating source narratives. It records mention/appearance, not culpability. Dates are transcribed from page titles where available; “Date not explicit in title” means the linked source must be consulted. Search indexing is a discovery aid, not proof of exhaustive external coverage. 🕒

Cross-reference — Cedwyn / Cydfin place-name evidence: References on this page to variants such as Cedwyn, Cydfin, Cedfin, Cydwin or Tŷ Mawr should be read alongside the GHF-E173 complete reference index and, where relevant, the Llandough (Penarth) pre-1877 manorial evidence page. Name similarity is a research lead, not proof of identical location, boundaries, ownership or title.

16 October 2026 — catalogue record 507738: “Eviction News Material”, 30 November 1988

Source link: Watch and Listen item 507738. The catalogue data supplied for this review describes a one-minute HTV Wales videocassette on ITV Betacam stock, with recording and broadcast dates both stated as 30 November 1988. The abstract describes Miles Fletcher pieces to camera, bailiffs removing furniture, removal vans and Branwen leaving the farm, and states the High Court granted an injunction stopping BP demolishing the farm.

Limits: the cataloguer’s note states “Not viewed”; the tape contains several unrelated clips and this clip’s position is unknown, so the description may come from the broadcaster’s log. The record as supplied has neither a catalogue-created date nor an online-publication date. Do not infer when the catalogue page went online from the event, recording or broadcast date.

Distinction and publication chronology: this 30 November eviction/injunction record is not the separate 5 December 1988 “Wales at Six” demolition headline/report. The project chronology records the YouTube viewing copy linked at GHF-E113 as published on 25 July 2025. That is not a date supplied by item 507738; the catalogue record has no catalogue-created or online-publication date in the information supplied. The relation between the cassette and YouTube copy and the uploader/source history remain unconfirmed. Search separately for 5 December HTV Wales items and log exact catalogue identifiers and search scope. Ask the Enquiries team/Beryl Evans when item 507738 was created and first published online, and whether a distinct 5 December demolition package is catalogued. A negative result should be recorded as a dated search result, not proof that no material exists.

Access and rights: the supplied record states that original materials are not circulated, digital viewing is restricted to Reader’s Ticket holders on Library premises, and reuse requires written permission from ITV Wales. Those ordinary stated conditions do not establish a case-specific NDA or concealment. Physical/digital inspection of the tape and any actual collection of media remain pending.

(b) Inconsistencies and gaps

“Not held” answers set against the duty below

Contradictions between replies, or between institutions

(c) Quarantined-name links

Records on the quarantine register (Kissed Frogs) that sit in, or came from, this institution’s holdings. None is treated as settled.

(d) Duty and liability — our reading

Liability indicators (our reading): strong

Duty
Custody and cataloguing of deposited records (Public Records Act 1958 for public records and places of deposit; the deposit terms for private collections); FOIA 2000 / EIR 2004 for information about holdings; an accurate catalogue is the finding aid the public relies on.
Indicators the duty was not met
replies that do not agree; “not held” answers.
Evidence still needed to confirm
the institution’s retention schedule and disposal record for the series in question; the catalogue or file list it searched; the original items on the quarantine register; any internal review or complaint outcome.
Likely extent of exposure if confirmed
Limited to the custodial record unless a mis-catalogued or withheld item is shown to have kept evidence from a decision-maker; then it may extend to the cost of putting the record right.

(e) Evidence still needed
