The Electromagnetic Telegraph
- Spokane Chapter Morse Telegraph Club. Reminiscences of railroad telegraphers; the personal side. Includes links to other sites.
- Civil War Signals: an interesting site concerned with flag and electromagnetic telegraphy of the Civil War. It wants to put an astounding number of cookies on your computer at every click, which I reject, but I am sure there are no ulterior motives, just an enthusiastic programmer. It contains links to other telegraph sites.
