[GreenKeys] Anyone have a (digital) copy of these? & Thanks for all the help!

[DR HOUSE]

Some of these texts are very large.  (over 3 inches thick)
I doubt they are available in a digital format,
however I have been wrong many times.

I bought my copies at http://www.abebooks.com/
and on eBay.

Good luck,
Don K9TTY

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

Many thanks to anyone who can provide any help!

Cheers,
Christian M. Gauger-Cosgrove
