Short will consult the convenience of his readers if he uses the English forms of names like Homer, Horace, Virgil, in place of Homerus, Horatius, Vergilius.
The vernacular names of the Middle Ages often appear in various forms. The form which has survived to the present time is to be preferred (as Jean to Jehan), unless a name is commonly used in the old form, as in the romances Jehan de Lançon. Refer from the one not chosen.
28. If an author has written in several modern languages, choose that in which he has written most.
29. In languages which use a masculine and a feminine form of family names (as Modjeski and Modjeska), use that which the authoress herself chiefly employs.
30. When an author’s name is variously spelled, select the best authorized form as heading, add the variants in parentheses, and make references from them to the form adopted.
Of course, great care must be taken not to enter separately works in which an author spells his name differently, as Briant and Bryant, Easterbrookes and Estabrook, Erdmann and Erdtmann. On the other hand, different people who spell their names differently should be separated, as Hofmann and Hoffmann, Maier, Mair, Majer, Mayer, Mayr, Meier, Meir, Mejer, Meyer, Meyr, Schmid, Schmidt, Schmied, Schmiedt, Schmit, Schmitt. (On the arrangement of such names in a card catalogue see § [218].)
In German Christian names there is a want of uniformity in the use of C and K (Carl, Conrad, Karl, Konrad) and f and ph (Adolf, Adolph). Occasionally an author uses both forms in different books, or writing only in Latin (Carolus, Rudolphus), does not show which form he prefers. Where the author thus leaves the point undecided, K and f should be preferred to C and ph (except in Christoph). Swedish f is to be preferred to v, as Gustaf, not Gustav.
31. When family names are written differently by different persons, follow the spelling adopted by each, even though it should separate father and son.
32. Forenames are to be used in the form employed by their owners, however unusual, as Will Carleton, Sally (Pratt) McLean, Hans Droysen, Fritz Reuter.
33. Give names of places in the English form.
