E. g., it will not do to confound works on the vegetable kingdom with works on vegetables, in the sense of kitchen-garden plants; the first would be properly entered under Botany. Ottley’s “Italian school of design” or a work on “Wagner and his school” are not to be put under Education. Special care is of course needed with foreign titles; the cataloguer may be easily misled by the sound if he is not on his guard. I have seen Lancelot’s “Jardin des racines grecques” classed with works on Gardening, Stephanus Byzantinus “De Dodone [urbe Molossidis]” put under Dodo with a reference from Ornithology, and Garnier “Sur l’autorité paternelle” among the works on the Christian Fathers.
(j.) Compound subject-names.
106. The name of a subject may be—
(a) A single word, as Botany, Ethics.
Or several words taken together, either—
(b) A noun preceded by an adjective, as Ancient history, Capital punishment, Moral philosophy.
(c) A noun preceded by another noun used like an adjective, as Death penalty, Flower fertilization.
(d) A noun connected with another by a preposition, as Penalty of death, Fertilization of flowers.
(e) A noun connected with another by “and,” as Ancients and moderns.
(f) A sentence, as in the titles “Sur la règle Paterna paternis materna maternis” and “De usu paroemiae juris Germanici, Der Letzte thut die Thüre zu;” where the whole phrase would be the subject of the dissertation.
