Hello Hive,
I wonder if I could please ask those of you with big, fantastic brains to answer this question for me?
Before 1958, you would have to call numbers via an exchange? For example SAM 218.
After 1958, I understand that you could call directly. As in, you don't need to go through an exchange.
Would that mean the number SAM 218 changes completely?
It's for a book. Thanks so much.
