The book on Italian sculpture raises a very troublesome question in connection with subject-entries for the dictionary catalogue, namely, whether double entry is required or not. The youthful beginner may be told here, as a kind of aside, that there is no third subject to this book, it has nothing to do with "Evolution" as such. The book is not upon sculpture as a whole, but upon that subject with a geographical (or national) limitation, yet the prominence of Italian sculpture in that art calls for an entry under "Sculpture," as shown above. The book, moreover, is not specifically upon Italian art, but only upon a phase of it, yet those who want to study Italian art in all its aspects must have their attention directed to it. Accordingly we either need an entry, as
| Italy: | |
| Art. | |
| Crawford, Earl of. The evolution of Italian | |
| sculpture. 1909 | 784 |
or the more economical reference:—
Italy:
Art.
See also Sculpture.
When space is a consideration, then the reference will suffice, but where it can be afforded, double entry is advised. If there are many entries under such a heading it can be sub-divided to simplify reference—divisions as "General," "Greek and Roman," "Italian," "British," suggest themselves, though the amount of sub-division usually depends upon the material to be arranged. The heading need not necessarily be the geographical one (Italy), as here shown; a term more direct, say "Italian Art," might be chosen.
In any case a book of this definite character would not be entered under "Art" in the dictionary catalogue, sculpture being but a branch of the Fine Arts, as also are painting and architecture. The heading "Art" then would be reserved for books dealing with art generally, including all the arts, or, at least, the two principal, painting and sculpture, which people mostly mean when speaking of art, though in no case must the valuable guiding reference be omitted
Art:
See also Sculpture.
Furthermore, there is no reason why this heading should not be reserved for books upon art generally without a qualification, and the books upon national art be placed under the names of the country concerned, with a further reference of a comprehensive nature, to this effect
