A structured compilation of telephone numbers, generally organized alphabetically by subscriber name or by location, enables the efficient retrieval of contact information. These compilations can exist in physical (printed) or digital forms. An example includes a listing showing the name “John Smith” followed by the telephone number “(555) 123-4567” and possibly an address.
Such organized listings facilitate communication, allowing individuals and businesses to readily connect. Historically, these listings were essential for establishing and maintaining telecommunications networks. They streamlined the process of finding needed contact details, improving operational efficiency for businesses and facilitating personal correspondence.
The design and structuring principles applied to these information repositories remain relevant in the development of modern contact management systems and digital address books. Further considerations involve data security, privacy regulations, and adapting presentation methods to various platforms.
