Ben Franklin’s Almanacs are collectibles in Assassin’s Creed 3, which are basically pages from the book he is compiling. You will be given this side mission when you first encounter Ben Franklin in the streets of Boston just as you are making your way to the shop.
There are four of these pages scattered throughout Boston and collecting them all will complete one volume of Ben Franklin’s Almanacs. Completing one volume will unlock Blowing in the Wind achievement or trophy. For more help on Assassin’s Creed 3, read our Peg Leg Trinkets, Treasures and Feathers Locations.
