Each book can have a cover image and one linked manuscript. Both are on the **Details** tab of the book form.

## Add a cover image

1. Go to **Book Library** and open the book, or click **Add New Book**.
2. Scroll down to **Cover Image** on the **Details** tab.
3. Click **Upload cover file** and choose an image, or paste a link to an image under **or paste a URL**.
4. Check the preview, then click **Save Changes** (or **Add Book** for a new book).

Cover files must be JPEG, PNG, WebP or GIF images under 10 MB. Uploaded covers are saved where your files are stored: built-in storage, or the Dropbox or Google Drive account you chose in **Settings**.

A cover you paste as a link stays a link. If the website hosting it removes the image, your cover will disappear too. Uploading the file is more reliable. Covers you pick from a title search are saved to your storage for you.

## Attach a manuscript

1. Open the book and go to **Manuscript** on the **Details** tab.
2. Either:
   - Click **Upload new**, choose a PDF or EPUB file, then pick the Storage folder to put it in, or
   - Click **Choose from Storage** to link a PDF or EPUB you've already uploaded.
3. Click **Save Changes**.

To unlink the manuscript, click the **x** next to its name and save. The file stays in Storage.

## Put a book's files in a folder

Use the **Folder** field on the **Details** tab to give the book a Storage folder. New manuscripts you upload for that book are suggested for the same folder. Choose **+ New Folder…** to create one.

## Tip

To start a new book from a file, drag a cover image or a PDF or EPUB onto the app and drop it on **Add Book (cover)** or **Add Book (manuscript)**. A new book form opens with the file ready to use. A spreadsheet dropped on **Book Importer** opens the importer instead.
