The World’s First Telephone Book
The world’s first telephone book has just found in Connecticut. It was 20-page directory and issued in November of 1878. The phone book contained information useful to 391 subscribers within the Connecticut. It says that “Should you wish to speak to another subscriber you should commence the conversation by saying, ‘Hulloa!”.
It also says that “Never take the telephone off the hook unless you wish to use it”. When you are talking to other subscriber, say “That is all”, and the person on the other end should say “O.K.”, only then you can hang up. The book also tells the users “lower lip and jaw free.” Users are warned not to use the phone for more than 3 mins at a time and no more than 2 times an hour without getting the permission from the main office.
