These maps are all available in game, meaning you don't need any handholding to find them all! The convenience of having the chests, feathers, and almanac pages on your mini map and on your in-game maps is invaluable. It means you don't have to sit here and read someone else poorly describe these locations!
Assassin's Creed III lets you purchase the maps in-game, adding all of the collectibles to your Animus map. All you have to do to purchase these maps is complete Sequence 04 and then purchase them from the local shops in the cities and frontier.
All general stores have identical inventories. There are three general stores in Boston, New York, and the Frontier each. Finding these physical locations also allows you to trade with these merchants by Convoy. Don't sell your game or other junk directly. Higher profits are almost assured via Convoy instead. Here are a list of maps and their prices:

Frontier - Chests - 3000
Black Creek - Feathers - 2500
