• Scanned old yellow pages are not a suitable format, even for reading. Forget it if you plan to do research, as this format is not searchable. I find I have to constantly switch back from the overview to the desired page to be read, one page at a time. Better to pick up a hard copy of a reprint or edited version and skip the digital format as it is very inconvenient and virtually useless. It was .99 cents, so I guess you get what you pay for.
