Many books have “Unknown” in the title or author field: if you are a reader, this could get annoying. Even if your conversion software doesn’t know how to fill in your metadata correctly, you’ll see something there. No matter which software you used to create your epub file, your epub already has some metadata: title, language and an identifier are mandatory for all ebooks. If your metadata is encoded in the book, our system will automatically be able to read it and fill in the necessary fields.

The best additional benefit of accurately encoded metadata is that you don’t have to enter your metadata manually when uploading your book to PublishDrive. Books with metadata not correctly encoded might not display author or title correctly on the reader’s device.
