Calling someone?
Back in the day, if you wanted to call someone and you didn't have a telephone number, you could call the number information service 008. You got the telephone operators on the line who helped you look up the number. In the carousel archive above the ladies or in one of the books they could usually find the right telephone number, see attached photo from 1966. The number of inquiries for telephone numbers via a telephone operator reached its peak in the mid-1990s. More than 100 million times the intelligence service was called asking for a telephone number.
