The letter "Å" (HTML å) was introduced in Norwegian in 1917, replacing "Aa" or "aa". The new letter came from the Swedish alphabet, where it has been in official use since the 16th century. Similarly, the letter "Å" was introduced in Danish in 1948, but the final decision on its place in the alphabet was not made. The initial proposal was to place it first, before "A". Its place as the last letter of the alphabet, as in Norwegian, was decided in 1955. The former digraph "Aa" still occurs in personal names, and in Danish geographical names. In Norway, geographical names tend to follow the current orthography, meaning that the letter "å" will be used. Family names may not follow modern orthography, and as such retain the digraph "aa" where "å" would be used today. "Aa" remains in use as a transliteration, if the letter is not available for technical reasons. "Aa" is treated like "Å" in alphabetical sorting, not like two adjacent letters "A", meaning that while "a" is the first letter of the alphabet, "aa" is the last. In Norwegian (but not in Danish), this rule does not apply to non-Scandinavian names, so a modern atlas would list the German city of Aachen under "A", but list the Danish town of Aabenraa under "Å". In Danish, the "aa" rule is applied, as long as it denotes one sound, for example German Aachen or Dutch kraal, but if it denotes 2 sounds like in "ekstraarbejde" (extra work), the two "a"s are sorted as two. The difference between the Dano-Norwegian and the Swedish alphabet is that Swedish uses the variant "Ä" instead of "Æ", and the variant "Ö" instead of "Ø", similarly to German. Also, the collating order for these three letters is different in Swedish: "Å, Ä, Ö". "Æ" and "Ä" are sorted together in all Scandinavian languages, including Finnish, as are "Ø" and "Ö". In current Danish and Norwegian, "W" is recognized as a separate letter from "V". In Danish, the transition was made in 1980; before that, the "W" was merely considered to be a variation of the letter "V" and words using it were sometimes alphabetized accordingly (e.g., "Wandel, Vandstad, Wanscher, Varberg" in "Dansk Biografisk Leksikon", 1904).
