Initially each entry is empty, with a silhouette of the missing entry. After a required collectible is collected a message notifies the player that they've added an entry to their collection, and the image appears inside the collection window. Mousing over the image will display a description for that entry.
Collection requirements for pets, action figures, cooking, fossils, and bugs can be completed by sharing the required item with other players. Fishing must be completed by the character, because the entries are filled when the fish is caught using a Fishing Rod.
Collections are filled in per character, so each individual character has their own completion for their collections. Filling in collections has no impact on gameplay and isn't required for any progression.
After completing an entire collection a gold star will appear on that collection tab inside the Collections Library window.
