LC-PCC Policy Statements for RDA 16.2.2.3 and 16.4 state: “Follow the British Library’s practice of using “Great Britain” as the conventional name for the government of the United Kingdom.”
Equivalent guidance for official RDA is found in these LC/PCC MGDs for elements Access Point for Place and Preferred Name of Place:

On February 19, 2025, Judith Cannan, then chief of PTCP, announced on PCCList in response to feedback about tentative monthly list 2412a received during February 13-18. Her response indicated that “The Library of Congress defers to the United States Board on Geographic Names (BGN) for place names contained within our controlled vocabularies and classification. For more information, please see our Subject Headings Manual sheet H 690 Formulating Geographic Headings and visit the BGN webpage.”
The BGN form for this jurisdiction is United Kingdom, not Great Britain. Great Britain, meanwhile, is a separate entity in BGN, an island that is separate from the island that includes Northern Ireland, which is part of the jurisdiction known more fully as United Kingdom of Great Britain *and* Northern Ireland. So, the conventional name “Great Britain” is both inaccurate with respect to Northern Ireland, and also goes against the stated deferral to BGN. There would understandably be a massive amount of file maintenance involved in changing this long-standing exception in both the NAF and LCSH, but the MGD does not reveal any principled justification for keeping this exception except that it’s BL practice. On the other hand, if an exception to the BGN can be made on behalf of the British Library, I find it hard to accept that LC is unable to make exceptions in other cases and had no choice but to defer to the BGN’s decision to change “Mexico, Gulf of” to “America, Gulf of.” Couldn’t we just as easily introduce a Policy Statement/MGD that says “Follow Biblioteca Nacional de México’s practice and use the name ‘Mexico, Gulf of'” or other similar exceptions? We can anticipate other attempts to rename or claim jurisdiction over other places and features, and that BGN, which reports to the Secretary of the Interior, will follow. LC is understandably a federal agency but does not report to the Secretary of the Interior, and neither does PCC, which is non-governmental and has international membership.
So, if the deferral to BGN with respect to geographic names is as absolute as claimed by LC, I think these steps would be necessary: 1. Revise all LCSH and NAF headings using the form “Great Britain” for the jurisdiction. 2. Make a separate LCSH for “Great Britain” representing only the island, and revise the scope note for existing LCSH “British Isles“. 3. Remove the exceptions found in the MGDs/PSs mentioned above.
Or if not: Revise LC/PCC policy (including SHM H690 and the LC PCC PS/MGDs mentioned above for the RDA element: preferred name of place and access point for place, mentioned above), to give greater weight to other authoritative sources besides GNIS/BGN. This seems especially true for establishing or changing names of international waters, disputed territories, and other geographic features shared across tribal or national jurisdictions.
