This is a matter that might be settled by calculation, and it would be well worth while to settle it. Mr. Cutter says that ninety-nine in a hundred must look under the title first, but I doubt if the percentage be quite as high as this. If it were, it ought to be conclusive against any other arrangement than that under titles.
Moreover, these instances do not really meet the case, for they belong to another class, which has to be dealt with in cataloguing—that is, those who change their names. When a man succeeds to a peerage he changes his name just as a Commoner may change his name in order to succeed to a certain property.
8. Foreign compound names to be arranged under the first name, as Lacaze Duthiers. English compound names under the last, except in such cases as Royston-Pigott, where the first name is a true surname. The first name in a foreign compound is, as a rule, the surname; but the first name in an English compound is usually a mere Christian name.
This rule is open to some special difficulties. It can be followed with safety in respect to foreign names, but special knowledge is required in respect to English names. Of late years a large number of persons have taken a fancy to bring into prominence their last Christian name when it is obtained from a surname. They then hyphen their Christian name with their surname, because they wish to be called by both. The Smiths and the Joneses commenced the practice, but others have followed their lead. The indexer has no means of telling whether in a hyphened name the first name is a real surname or not, and he needs to know much personal and family history before he can decide correctly.
Hyphens are used most recklessly nowadays, and the user has no thought of the trouble he gives to the indexer. If the Christian name is hyphened to the surname, and all the family agree to use the two together as their surname, the indexer must treat the compound name as a true surname. Often a hyphen is used merely to show that the person bearing the names wishes to be known by both, but with no intention of making the Christian name into a surname. Thus a father may not give all his children the same Christian name, but change it for each individual, as one son may be James Somerset-Jones and another George Balfour-Jones. In such a case as this the hyphen is quite out of place, and Jones must still be treated as the only surname. No one has a right to expect his Christian name to be treated as a surname merely by reason of his joining the Christian name to the surname by a hyphen. He must publicly announce his intention of treating his Christian name as a surname, or change it by Act of Parliament. Even when the name is legally changed, there is often room for confusion. The late Mr. Edward Solly, F.R.S., who was very interested in these inquiries, drew my attention to the fact that the family of Hesketh changed their name in 1806 to Bamford by Act of Parliament, and subsequently obtained another Act to change it back to Hesketh. The present form of the family names is Lloyd-Hesketh-Bamford-Hesketh.
With respect to Spanish and Portuguese names it is well to bear in mind that there are several surnames made from Christian names, as, for instance, Fernando is a Christian name and Fernandez is a surname, just as with us Richard is a Christian name and Richards a surname.
9. An adjective is frequently to be preferred to a substantive as a catchword; for instance, when it contains the point of the compound, as Alimentary Canal, English History; also when the compound forms a distinctive name, as Soane Museum.
The object of this rule is often overlooked, and many indexers purposely reject the use of adjectives as headings. One of the most marked instances of an opposite rule may be seen in the index to Hare's Walks in London (1878), where all the alleys, bridges, buildings, churches, courts, houses, streets, etc., are arranged under these headings, and not under the proper name of each. There may be a certain advantage in some of these headings, but few would look for Lisson Grove under Grove, and the climax of absurdity is reached when Chalk Farm is placed under Farm.
10. The entries to be as short as is consistent with intelligibility, but the insertion of names without specification of the cause of reference to be avoided, except in particular cases. The extent of the references, when more than one page, to be marked by indicating the first and last pages.
This rule requires to be carried out with judgment. Few things are more annoying than a long string of references without any indication of the cause of reference, but on the other hand it is objectionable to come across a frivolous entry. The consulter is annoyed to find no additional information in the book to what is already given in the index. It will therefore be found best to set out the various entries in which some fact or opinion is mentioned, and then to gather together the remaining references under the heading of Alluded to.
