Before caller display, the phone book, also known as the telephone directory, was how we found people. No internet, no Google and certainly no GPS or location based services, this hands on approach - literally - allowed our fingers to do the walking while we perused the tens of thousands of names in the heavy but necessary tome. Found in every household, the telephone book was where we located names, addresses and phone numbers, though no corresponding selfies or social media handles accompanied them. In fact, in these times that predated Social Media altogether, we kicked it old school with just the printed information on the page and guess what? We were fine.
