The alphabet demands this, and I see no reason to make an exception
which can not be made in foreign languages.
«Bride» of Lammermoor.
«Brides» and bridals.
«Bride’s» choice.
«Boys’» and girls’ book.
«Boy’s» King Arthur.
«Boys» of ’76.
226. Arrange Greek and Latin personal names by their patronymics or
other appellatives.
_Ex._ «Dionysius.»
«Dionysius» _Areopagita_.
«Dionysius» _Chalcidensis_.
«Dionysius» _Genuensis_.
227. Arrange English personal names compounded with _prefixes_ as
single words; also those foreign names in which the prefix is not
transposed (see § 24).
_Ex._ «Demonstration.»
«De Montfort.»
«Demophilus.»
«De Morgan.»
«Demosthenes.»
Other such names are Ap Thomas, Des Barres, Du Chaillu, Fitz Allen, La
Motte Fouqué, Le Sage, Mac Fingal, O’Neal, Saint-Réal, Sainte-Beuve,
Van Buren.
This is the universal custom, founded on the fact that the prefixes
are often not separated in printing from the following part of the
name. It would, of course, be wrong to have «Demorgan» in one place
and «De Morgan» in another. {86}
228. Arrange personal names compounded of _two names_ with or without a
hyphen after the first name but before the next longer word.
_Ex._ «Fonte», Bart. de.
«Fonte Resbecq», Auguste.
«Fontenay», Louis.
«Fontenay Mareuil», François.
229. In the preliminary card catalogue it is best to arrange these by
the first name, neglecting the second entirely[67] and subarranging by
forenames.
The reason is (1) that authors do not always use the second part of
their names, and (2) that the single alphabet is easier to use in a
card catalogue.
_Ex._ «Halliwell» (_afterwards_ «Halliwell-Phillipps»), James Orchard.
[note] 67. Except when the first family names and forenames of two
persons are the same, when the one with a second part will come after
the other; but if both have a second part, subarrange by these second
parts when they differ.[/note]
