To most, an ISBN is just a random assortment of figures much like a bar code, but to these in the ebook industry it’s a distinctive industrial guide identifier. The ISBN was invented by Gordon Foster, an Emeritus Professor of Stats at Trinity College in Dublin, in 1966. It was originally a 9-digit number, but it was increased to 10-digits in the , and 13-digits in 2007. So how does one go about reading an ISBN?The initial point to notice is that ISBNs are intended to be study from left to proper. The is that the important parts of an ISBN are separated by either a place or a hyphen (as in the instance underneath). The third point to be aware is that an ISBN will have either 4 or 5 areas – 4 parts in the situation of a 10-digit ISBN and 5 areas in the case of a 13-digit ISBN.

The 3-digit GS1 prefix is also sometimes referred to as an European Report Amount (EAN) or an International Write-up Number (IAN).
