Hello everyone!



First I want to give a great big thank you for all the help and

pointers I was given in my earlier request for documentation. I''ve

also found much help from my local university's engineering library.



Now, I'm just wondering, might anyone have a digital copy of the

following texts by any chance?

1. "A History of Engineering and Science in the Bell System: The early

years (1875-1925)" Amos E. Joel, Bell Telephone Laboratories, G. E.

Schindler

2. "A History of Engineering and Science in the Bell System: Switching

technology (1925-1975)" M. D. Fagen, Amos E. Joel, G. E. Schindler,

Bell Telephone Laboratories

3. "Telephony and Telegraphy: An Introduction to Instruments and

Switching Systems (Electromechanical and Reed-Electronic)" Sydney F.

Smith

4. "Introduction to Telephone Switching" Bruce Edwin Briley
