To find lost ISBN numbers of books, you can start by checking online databases such as WorldCat or Google Books, which often provide ISBN information for a wide range of titles. Additionally, you can look up the book on the publisher's website or consult library catalogs. If you have a physical copy, the ISBN is typically found on the back cover or inside the copyright page. Lastly, book retailers like Amazon may also list the ISBN in their product details.
