Maps

Here you will find a collection of historic maps of telephone and telecommunications lines. They are collected from various sources, many of which were already secondhand collections—so a source is noted when possible, but it's hard to be 100% certain where these all came from. The maps are presented by the year they were created and the name shown on the map, when possible. The number in brackets is a TD-2 Control Number, a scheme invented just to make it a little easier to refer to specific maps when they come up in different places online.
