In the good old days while employee at TPC , a look at database a pain on a data terminal.
A trip to Kirsten business library in Boston or any major city, and a manual scan of “The Blue Book” would produce the name, address, or any number reverse search style.Listed or unlisted or so called private, non-published.
Both still exist and probably are how most reverse search companies still get their numbers, for a starting point. By a rather pricey subscription cost weekly or monthly. Reason for business library.
False telephone numbers are a whole nother problem.
Back to my phone call, it was a scam, false representation. I didn’t fall for it. I did swear to press charges against them.
And that’s it. One little codicil it’s been approx 40+ years since I worked for TPC (It’s an old Godfrey Cambridge movie line.)
Might or might not be called Blue Book still, whether in data form or printed.
And yes, after long days/nights, I'd still like to swing these hunks of glass , plastic and silicon against the nearest wall Come on retirement!
