Catalogues compiled upon very exact lines occasionally reserve the popular name for books of a popular or miscellaneous nature, and the scientific for those intended for the scientist, but the dividing line between the two classes of books cannot always be clearly seen, and it is much better to bring all together under the same heading, marking there any differences in the character of the books by means of sub-division.
In some few instances the use of the scientific term is unavoidable as there may be no popular name that meets the case. For example, it would not be correct to put a book upon the fresh-water algæ under a heading “Sea-weeds,” and a book upon the tunicata cannot be put under any other name. The fact may be again emphasised that in a dictionary catalogue a book is entered under its definite subject and never under its class or general subject. Thus a book like
White, W. F. Ants and their ways,
does not go under “Insects,” or even “Hymenoptera,” but directly under “Ants,” though such a book as
Lubbock, Sir John. Ants, bees, and wasps.
would be sufficiently entered in the catalogue of a scientific library, if placed under “Hymenoptera,” but in the catalogue of a popular library should go under all three names, “Ants,” “Bees,” and “Wasps,” just as a book like
Meyrick, E. British lepidoptera.
is better placed under “Butterflies” and “Moths” with a cross-reference
Lepidoptera. See Butterflies. Moths.
