"Thanks a lot, Doyle, this is very helpful! Is that telegraph book available for public research? Transcription? Microfilm?"

The Peter Wellington Alexander Papers on microfilm are available at the University of Arkansas Library. I believe they are also available in Little Rock at I believe the Arkansas History Commission.
The Columbia Universary Library also has website and the last time I looked the Alexander Papers index was listed. The Columbia Library will sell copies of their microfilms for research, but they retain copyrights against publishing.
