My main bathroom reading now is the 2nd edition of Engineering and
Operations in the Bell System, circa '84.  I LOVE THAT SHIT.

I have the '77 edition too, but the '84 version is even neater.  They
did it as the "final" edition, as there's a preface note about the 
consent decree/breakup.

Am I the only person who thought that things worked better when AT&T
was in charge of it all from end to end?
