What's the difference between ISBN-10: and ISBN-13:?

I was just shopping at amazon.com and I saw that most books had two different ISBN numbers. What's the difference between the two?|||hi john


Both ISBN-10 and ISBN-13 on copyright page


ISBN-10 (have10 digit)and


ISBN-13 (have 13 digit)


for example


ISBN-13: 978-1-56619-909-4


ISBN-10: 1-56619-909-3

hope you a nice day|||ISBN is The International Standard Book Number, or ISBN (sometimes pronounced "is-ben"), is a unique identifier for books, intended to be used commercially. There is another quite similar system, the International Standard Serial Number (ISSN), for periodical publications such as magazines. 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. It was adopted as international standard ISO 2108 in 1970.





The other ISBN -13 is the stores' in-house reference series of which 9 of the numbers should be the same.|||right now the book system is transitioning between the two systems. eventually they are going to move to just ISBN-13, i'm pretty sure.|||Hi John Doe,
