Listed: every name whose outline IntMap draws inside 82°W–34°W, 56°S–13°N on this date, with the name the map writes on it. The list is worked out when the site is built, from the same records and the same code the map uses, so it says what the map shows — not more. Names are the source’s own, translated where the source or IntMap’s name table has a translation.
