UPC codes are traditionally 12-digit codes (and are also frequently re-used and unreliable). And many DVDs have been assigned ISBNs because they are in the book supply chain – B&N sells quite a few DVDs, for example. So some studios got in the habit of requesting blocks of ISBNs for assignment, for the bookstore market.
Mac, I believe that those are UPC codes - barcodes - but not ISBNs.
Does anyone know for sure? Laura?
From the Bowker site:
"
The ISBN identifies a book or other book-like
product (such as an audiobook) in a specific format and edition,
but also the publisher."
and from their FAQ:
| DVDs |
DVDs may not get an ISBN if they are
entertainment or performance videos. If the DVD is
instructional or educational, then the DVD is eligible for
an ISBN. However, retailers vary in their requirements
regarding the type of product identification. Publishers
should check with their retailers for requirements. If the
DVD is eligible for an ISBN, the ISBN is placed near the
copyright line on the packaging. |

Karen said concerning ISBNs:
... it's only be in use for the last 50 years of book publishing, only covers books ...
About 1/3rd of the DVDs we do now have ISBNs, as well as often other
standard numbers. While it is true books published earlier lack
ISBNs, so do some modern books.
There is also the question of erroneous ISBNs, and a single
manifestation with more than one ISBN, e.g., simultaneous publication,
different bindings.
There are also several other standard numbers for books and
bibliographic records to be considered.
