Collections
From Destiny 1 Wiki
Collections are storage terminals found in The Tower. They keep track of collectible items such as Emblems, Shaders, Ships and Sparrows. Each Collection not only keeps track of the items you have acquired but also shows you where to get the items you don't have.
Players can generate a copy of the item (Emblem, Shader, Ship etc.) they have collected at any time.
Exotic Blueprints are collections for your Exotic Armor and Weapons.
