Extracts from single works come immediately after the respective works.

A spurious work is arranged with the single works, but with a note stating the spuriousness. But if the author’s name is used as a pseudonym the entry should have a separate heading after all the works; as, Browne, H. History. Browne, H., pseud. Stones from the old quarry. See Ellison, H.

If there are only two joint authors both may appear in the heading, but the entry should be arranged among the works written by the first author alone; if there are more than two the heading may be made in the form Smith, John, and others. The usual practice hitherto has been to arrange entries by joint authors after the works written by the first author alone, and this was recommended in the first edition in regard both to the form of the heading and the arrangement; but although it is pleasing to a classifying mind, it is practically objectionable because a reader, not knowing that the book he is looking for is a joint production, and not finding it in the first {89} series of titles, may suppose that it is not in the library. This danger is greatest in a card catalogue, where it entirely overweighs the somewhat visionary advantage of the separate arrangement. The arrangement of a card catalogue should be as simple as possible, because the reader having only one card at a time under his eyes can not easily see what the arrangement is. On the printed page, where he takes in many titles at a glance, more classification can be ventured upon; there the danger is confined to the more voluminous authors; where there are few titles the consulter will read them all and so will not miss any. On the printed page, too, the mixing in of joint authors interrupts to the eye the alphabetical order of titles; e. g.,

Dod, T. Anamites and their country.

— and others. Barracouta.

— Carriboo, a voyage to the interior.

— and White, E. Dahomey and the slave trade.

— Elephanta, its caves and their images.

This trifling inconvenience can be easily avoided, however, by including the second name in the title; e. g.,

Dod, T. Anamites.
