yellow pages

a section of the phone book with a list of the names, addresses and phone numbers of organizations and firms in an alphabetical order

The yellow pages are a section of a phone book or directory that lists businesses, organizations, and services categorized by type, such as restaurants, plumbers, or medical professionals. The listings are usually organized alphabetically within each category, making it easier for people to find specific services. The yellow pages were traditionally printed on yellow paper and were commonly used before the Internet became widespread. They served as a valuable resource for individuals searching for local businesses and services, although online directories and search engines have largely replaced them.
