No cross-reference being called for to “Chimpanzees,” as they are included in the title of the book under “Gorillas.” In the event, however, of there being a second book upon Chimpanzees, then the cross-reference becomes
Apes.

87.—At the risk of repetition, and to make the matter clear, it may be again stated that a book must not be entered under every important word appearing upon its title-page. There is much rule-of-thumb cataloguing done that would cause a book like
Ihering, Rudolph von. The evolution of the Aryan,
to be entered under “Evolution,” whereas not even a title-entry under the word “evolution” is required, and the single subject-entry is

It may be considered unnecessary advice to say that a book so unmistakably upon the Aryan peoples should not be put under “Evolution,” when the accepted meaning of that term as a subject has nothing to do with it, yet there are catalogues at present in force of important town libraries with much worse forms. One has a heading “Natural history,” under which there are sixteen items that include such diverse matters as “Natural method of curing diseases,” “Natural theology,” “Natural philosophy,” “Nature and art,” “Drawing from nature,” because the word “natural” or “nature” happened to occur in the titles of the books. Another has a heading “School, Schoolmasters, and Schools,” which includes Molière’s “School for wives” and his “School for husbands.” Any number of examples equally ridiculous could be quoted from present-day catalogues to prove the contention that this is a common form of error. Therefore the advice to “get at the subject of the book, and never mind the particular words used on the title-page,” cannot be too often impressed upon the cataloguer.
