The Southbound edition is best suited for hikers planning north-to-south trips on the A.T. All of the data is the same as what is in the northbound edition, but it is presented in front-to-back, top-to-bottom order with mileages starting from Mt. Katahdin.

The Unbound editions are the same, except there is no binding. Pages come in heavy-duty zip-lock bag. This edition is most useful for hikers who want to carry only relevant sections of the book.
