In Upjohn days, paper phone books were still the norm. In the 1980s we got a new phone book every summer and winter. I've scanned the entire 1977 phone book, the Winter 1989/90 phone book and the Winter 1994 phone book. Also there are pages from the Summer 1985 phone book and some front covers of other phone books. Note the good advice on telephone courtesy in the 1985 issue.
