There are five groups of numbers, whereas the 10-digit ISBN had four groups. The actual ISBN (9781861978769) has been separated into groups by hyphens or spaces just to make it easier for humans to be aware of the different sections of the particular ISBN. When you look at the ISBN as printed above the barcode on the book shown in the photographs taken of the back cover and from the back of the title page near the front of the book, you can see it is separated into sections by hyphens or by spaces. The example is taken from the book 'Why Don't Penguins' Feet Freeze: and 114 other questions', edited by Mick O'Hare and published by Profile Books in 2006. We will take an example of a 13-digit ISBN to use in the discussion that follows. For further details of the history of the ISBN system, see the History of the ISBN system page. This revision mainly prevents the number of new ISBNs running out in the near future, but also integrates the ISBN system into the wider system of product numbering known as EAN which also uses 13-digits for a whole range of goods.
