31.—With the commoner surnames, as Smith, Brown, Jones, and the rest, there will be a number of authors who will have also the same Christian name, when particular care must be exercised not to mix the works together, and so attribute books to a wrong author. Some distinction must be given, like that shown in the “Taylor of Norwich” entry (p. 27), and these are better printed in italics. Examples of these, taken from a catalogue, are
Smith, John, A. L. S.
Smith, John, of Kilwinning.
Smith, John, of Malton.
Thomson, James (poet, 1700-48).
Thomson, James (“B. V.”)
Thomson, James (Traveller).
When father and son with the same name are authors, and the difference between them appears in the book as “the elder,” “jun.,” “fils,” “aîné,” &c., it should be given at the time the entry is made, even though not then required for distinguishing purposes, the library only possessing the works of one or the other. Frequently such a distinction is not shown on the book, and the cataloguer must add it. Strange to say, entries like the following have been seen in catalogues:—
Frères, P. Modes et costumes historiques.
