- ATC's official annual Appalachian Trail guide is the Appalachian Trail Thru-Hiker's Companion, compiled and updated by volunteers of the Appalachian Long Distance Hikers Association (ALDHA) (available at AppalachianTrail.org). Individual state guides and maps are also available via the ATC.
- The Official AT Databook, an annually updated compilation of trail mileages, water sources, road crossings, shelter locations, and other information. The 2015 DataBook is the 37th annual edition, is considered indispensable by many AT hikers, and the data published within is used by many other hiking guides.
- Another annual guide book to the AT is The A.T. Guide by David Miller, author of "Awol on the Appalachian Trail”
