Could these be them; or, are these not the same?

Employing the search term "Radio Instruments and Measurements" at:
http://www.kartoo.com/
you can make use of an unique, cluster based search engine that
represents the next wave of sifting information on the Web.

You will find references to this tome (hardly a circular or bulletin)
of more than 600 pages (you will also find book venders ready to sell
this work for $20-$30). One NIST site contains a quote from Edison:
" . . . This is the greatest book on this subject that I have ever
read, and I want to congratulate you and your Bureau on its
production."

There are multiple authors. I cited one, George Clark Southworth,
another was J. Howard Dellinger.

There are hard copies available through NIST's Historical Archives
(try to get one though).
