====== 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 M# 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. The Authority column contains any source markings from the map itself, typically date published and sometimes a drawing number.
