Hello, somebody has asked for a survey of national sorting rules. (I have already deleted that note.) Now it has occurred to me that the IBM National Language Technical Centre has produced a "National Language Information and Design Guide" comprising such a list (in Volume 2, Chapter 3). I have only the 1st edition of July 1987, which still contained many inaccuracies. I do not know whether these books have been overhauled, or whether they still are available. Check with your local IBM representative; order number was SE09-8002-00 (back in 1987).

German DIN 5007 (of April 1991) also has its peculiarities. It defines two, mutually incompatible, orders, one "for lists of proper names" and the other one for anything else. The former one is used by the descendants of the former German Postal Authority for their directories (telephone, zip-codes, &c.), and I think, this is the reason that it is still in the national standard (though with a note that it may be dropped in later versions of the standard); the latter one (or variants thereof, as exemplified below) is used in encyclopaedias and dictionaries. In 1st approximation, the former equates "ä", "ö" und "ü" to "ae", "oe", and "ue", respectively, the latter to "a", "o" and "u". Bothe equate "ß" to "ss", and "þ" to "th", in 1st approximation. (The "þ" ruke is an interesting quirk, as this letter is alien to German orthography.) Both are three-level sorts: 1st-approximation homographs are sorted, in 2nd approximation, by the letter variants, such as diacritical marks. Here, Umlauts ("ä", "ö", "ü") and the Eszet ("ß") go after base characters but before any other variant; DIN 5007 even defines a particular order for accents and similar diacritical marks (based on their glyphical appearance). 2nd-level homographs are sorted according to case: here, capitals go after small letters. Encyclopaedias and dictionaries usually comply with the 1st level. Some state explicit, deviating rules for the 2nd, or 3rd, level (e. g. Duden has "ß" before "ss", in the 2nd level); some do not state their rules in that detail, but nevertheless deviate in 2nd, or 3rd, level. Some dictionaries sort 1st-level homographs on part of speech. Best wishes, Otto Stolz
