We have earlier seen about the Web Directory, so today we will see facts on the Telephone Directory.

A telephone directory (also called a telephone book and phone book) is a listing of telephone subscribers in a geographical area or subscribers to services provided by the organization that publishes the directory. Thus it is necessary that there be different telephone directories in different geographical areas. Subscriber names are generally listed in alphabetical order, together with their postal or street address and telephone number in a typical Telephone Directory. The first telephone directory, consisting of a single page, was issued on February 21, 1878. It covered 50 subscribers in New Haven, Connecticut. There are different types of a Telephone Directory, usually named by the colour of the paper it is printed on. There are three mains types of telephone directories, and more colours do exist. Different colors may have different meanings, depending on a country's customs. Information on Government Agencies is often printed on blue or green pages.The three major types are:

1. White Pages which generally indicates personal or alphabetic listings.

2. Yellow Pages which generally indicates a business directory classified by business type or services provided, almost always with paid advertising.

3. Grey Pages which is also known as a reverse telephone directory.
