Book Library comes with a list of common tropes and built-in editions (Paperback, Hardcover, Hardcover w/ Dust Jacket, Limited Edition and eBook). You can add your own to both lists and use them on any book.

## Add tropes to a book

1. Open a book in **Book Library**.
2. On the **Details** tab, open the **Add a trope…** dropdown under **Tropes**.
3. Pick a trope from **Common tropes** or **Your tropes**, or choose **Other…** to type your own. Separate several with commas, then click **Add**.
4. Click **Save Changes**.

Any trope you type is saved to your own list, so it's there for your next book.

## Manage your tropes

1. On the **Book Library** page, click **Your tropes** (or **Manage your tropes →** in the book form).
2. Under **Add tropes**, type one or more tropes separated by commas to add them.
3. Use the pencil icon to rename a trope, or the trash icon to delete it.

Renaming or deleting a trope also changes it on every book that uses it. Before deleting, you're told how many books it will be removed from. The common tropes can't be changed.

## Add editions to a book

1. Open a book and find **Editions & Formats** on the **Details** tab.
2. Tick each format the book is available in.
3. To add your own, type it in **Add your own** (separate several with commas) and click **Add**.
4. Click **Save Changes**.

Your own editions also appear as choices on the **Inventory** tab, so you can count stock for them.

## Manage your editions

1. On the **Book Library** page, click **Your editions** (or **Manage your editions →** in the book form).
2. Add, rename or delete your own editions.

Deleting an edition takes it off your books. Stock counts and shipments you've already recorded keep the name. The built-in editions can't be changed.
