The proper title is:

" A History of engineering and science in the Bell System vol. 3.
Switching technology (1925-1975)", published by Bell Laboratories.

This should be found in most larger libraries, such as college
library. I strongly recommend it.

It is part of a series of books on the history of the Bell System. I
also recommend volume 1, "The early years (1875-1925)".
