Not from the Amazon page itself. Amazon blocks that, so Book Library looks the book up in Google Books, Hardcover, Apple Books and Open Library instead.

1. In Book Library, click **Add New Book**.
2. Choose **Create Manually** for one book, or **Bulk Search by Title** for several (one title per line, up to 500, then you pick each result).
3. For one book, under **Find your book by title**, choose **Published under** (your pen name), type the **Book title** and click **Search**.
4. Click **This one** on the right result.

That fills the title (using the catalogue spelling), series, ISBN-13, ASIN, description, genre, page count, publication date and cover, but only where a field is still empty. Your pen name is kept as the author.

Check the result before you save. Not every book is in those catalogues, and a title may not come back as an exact match. If nothing matches your author, you get results for the title alone, with a note to check the author on each one. If none is your book, choose **None of these, go back** and try another spelling, or add it yourself.

This needs an active trial or paid account.
