 | | However, ISBNs only identify a particular edition of a book, and the reader will not see the full range of versions of the book for sale. |
 | | ISBNs are sometimes referred to as "ISBN numbers", but since the "N" in "ISBN" already expands to "number", "ISBN number" is redundant, much like "ATM machine", "HTML language", "PIN number," or "RAS syndrome". |
 | | Also, note that a registered ISBN, even one which appears with a corresponding book page on a major book distributor database such as Amazon.com, is not definite proof that such a book exists. |
