Why is only one author’s name shown at the top of the CiP entry when the book has two or more authors?
In cases where a book has two or more authors, library cataloguing rules state that the first author mentioned on the title page must be used as the “main entry” on the cataloguing record; the other authors are recorded as “added entries” When a catalogue record is printed the main entry displays at the top of the catalogue record and the added entries appear after the description of the book. However, this format of main and added entries is a convention for display purposes only; added entries can be searched as well as the main entry in catalogues.
