ISBN
An International Standard Book Number (ISBN) is a numeric code used to uniquely identify a book, right down to the language, publisher, edition – and whether it is an ebook, paperback or hardcover. It makes life easier for booksellers, libraries, schools, book distributors, and anyone searching for a particular book.
