Your book’s metadata is the information attached to your book. Your book’s title, subtitle, author name, publication date, ISBN, and copyright are all a part of your book’s metadata. The actual content of your book is not a part of the metadata.Lulu collects the metadata for your book from different points in the publishing process. So, when you enter the book’s title and author name, you are setting up the metadata.Why is this important? It helps your customers to see all of the book’s information standardized. Also, if you’d like to have your book distributed by our partners when that option is available, the metadata must all match.
