I have done my best to collect all the old maps of the AT&T long distance system that I can find. Some of these are tricky to find these days. I am always interested in hearing about more maps, should you find any.

I often rehost maps here if I am concerned that the source will go offline, but if the source seems stable (like a library or other institution) I will link to the original source. Another note is that, for historic reasons (mostly having to do with where the telephone lines historically were), telephone maps of the northeast are relatively very easy to come by. Well, I live in the west, so I tend to only hang onto maps that are either nationwide or depict any of the western part of the country specifically.
