Add a World to a Collection when you want to group it with other reference material or return to it later without changing the World itself.

## What you need

- A Collection
- A World you own or a public World you can view

## Add the World

1. **Open the World.** Select it from the Library or Worlds feed.
2. **Open the World actions.** Tap **Collection**.
3. **Choose a Collection.** Select the destination Collection.
4. **Tap Done.** Open the Collection to verify that the World appears.

> Important: Adding a World to a Collection does not copy it, change ownership, or grant edit access.

## Troubleshooting

### Add to Collection is unavailable

Confirm the World is public or belongs to you, and create a Collection if none exists.

### The World appears twice

Open the Collection’s management controls and remove the duplicate entry. Removing it from the Collection does not delete the World.
