A bit about ISBN numbers (was Re: Minor Marx variant)

[Scot Kamins]

 From the usually unreliable but occasionally enlightening WIKIPEDIA:

"The International Standard Book Number, or ISBN (sometimes  
pronounced "is-ben"), is a unique[1] identifier for books, intended  
to be used commercially. The ISBN system was created in the United  
Kingdom in 1966 by the booksellers and stationers W H Smith and  
originally called Standard Book Numbering or SBN (still used in  
1974). It was adopted as international standard ISO 2108 in 1970. A  
similar identifier, the International Standard Serial Number (ISSN),  
is used for periodical publications such as magazines. From 1 January  
2007, ISBNs will be 13 digits long"
