yellow pages
Synonym discussion
Sense: phrase/1
Yellow pages, business directory, and classified directory all refer to listings of companies and service providers. Yellow pages is the most recognisable everyday term, originally linked to the yellow-paper phonebook section, and is often used as a proper noun (Yellow Pages). Business directory is a broader, more formal term — it can be a printed booklet, a website, or a chamber of commerce list. Classified directory emphasises the categorical organisation (under 'Plumbers', 'Restaurants', etc.) and may refer to the same thing but is less common in casual conversation. White pages is the opposite concept: it lists individuals by surname rather than businesses by category, so it is used when looking for a person's contact information rather than a service.
Etymology
The name comes from the yellow-coloured paper that the business-listing section of telephone directories was printed on, to distinguish it from the white-paper residential listings. The first dedicated yellow-pages directory was published in 1883 in Cheyenne, Wyoming, USA, after a printer ran out of white paper and used yellow paper instead. The term gradually became a generic name for any business directory organised by category.
