Fun Friday Fyi: A look back at phone system articles via Google and Popular Mechanics

Google has indexed many books, newspapers, photographic archives, images, videos, flash movies, PDFs, etc., and now they've added full archives of magazines. For example, I did a Google Book Search on "phone systems" and it returned a number of results from "Popular Mechanics".

A preview of the search results:

* New take-along telephone give you pushbutton calling to any number (1973)

* Here's Your Ultimate Telephone Center (1984)

* Phones on the Go (1984)

* How to Install Your Own Phone (1983)

* All of this technology can be understood if you know how the phone system beyond
the dial tone works. (1987)
