[GreenKeys] Principles of Electricity applied to Telephone and Telegraph Work

[Don Robert House]

I now have what I believe to be a relatively complete collection of 
the editions of Principals of Electricity applied to Telephone and 
Telegraph Work   published by A.T.&T. Long Lines Dept. as a training 
text for Long Lines employees - otherwise known as "the Green Book".

Previous to the first edition of the green book there was a limited 
distribution of Elements of Electricity Applied to Telephone and 
Telegraph Work, better known as Long Lines Training Course  #2 which 
was published in 1922.

The green book was first published in 1928, then revised and 
reprinted in 1929 as the second edition. Previous to 1929 
transmission measurements were made in Transmission Units (TU). 
Starting in 1929 the measurements were changed to "decibel' or dB. 
This being the only difference between the '28 and '29 editions.

The third edition was published in 1930.  The fourth edition was 
published in 1938 and corrected and reprinted in 1941. The fifth 
edition was published in 1953.  The sixth edition was published in 
1961.  I would like to know if any one has seen any editions of this 
textbook revised after 1961.  I am assuming that the "Red Books" may 
have taken over, but this is only an assumption.

Each book is interesting as over the years the advance of technology 
is shown.  Many things are added but also many things were either 
reduced in content or removed.  Terminology changes as technology 
changes.  In 1929 three sizes of copper cable are shown:  10AWG, 
13AWG and 16AWG
By 1961 the largest cables shown are 16AWG and 19AWG.  Frequency is 
still measured in cycles and kilocycles.

Here are the chapter titles from each of my editions:

Bottom Line is if you are looking for the most information on 
Telegraph Principles the coverage is going to be better in the 
1938/41 edition and the 1953 edition.  Only one chapter remains in 
the 1961 edition.
