buizer You don't get it. The way LD notates the ISBN in the appropriate field, with hyphens, is correct . The ISBN has traditionally been written with dashes (spaces are also allowed), not for readability (by humans or scanners), but because they distinguish the different digit groups that make up the number (you give an example yourself).

As online store Amazon shows the ISBN (as 1 number) is incorrect .
Bol does that too, but calls it what it is: EAN (or the product code).
The ISBN is translated into an EAN code, not vice versa.
And the EAN is translated into a barcode, not the other way around.

ISBN
Then a few observations.
I have never seen an ISBN number on the back of a book with 'underlying' bars below the ISBN barcode. So they are all listed incorrectly?
And that EAN (= product code) has assigned 978 and 979 as prefix to 'Books ISBN'.
And LD itself indicates in the manual to do it with underscores.
But I don't read anywhere that it is mandatory to do it this way (i.e. with underscores).
EAN and ISBN are both based on GTIN13.
So when it comes to scanning, there are no dashes...
And after 2007, ISBN and EAN krek are the same number. Or not?
And in/on LD it should not be scanned...
And whether you speak of ISBN, UPC or EAN itself: they are all product codes.
Provided that if when we talk about books, we talk about an ISBN number that always starts with 978. And are they already working on 979?

No, but those are not ISBNs either.
In a previous post I referred to the link of Leike-2.
The ISBNs are above the barcode, the EAN is below it.


Wikipedia no longer mentions it, but the official instructions for listing an ISBN (I had to study them extensively in the early 1980s, because of my position), did indeed mandate the use of dashes .
The ISBN (10-digit) existed before barcodes were introduced. Until 2007, ISBN and EAN were different. Now they are equal (in terms of numbers), but that doesn't mean they are the same.

Boekenmagazijn that 5 piece barcode > EAN-5 currency indicator for books in English: The first digit of the EAN-5 is the currency indicator. If set to 0 or 1, the price will be displayed in GBP (£). 5 is US$, 6 is Canadian $, 3 is Australian $ and 4 is New Zealand $. The next four digits represent the price multiplied by 100. For example, 50799 means that the price for this book is $7.99. If the last four digits are 9999, it means that the price is greater than (or equal to) 99.99 in the given currency.

ISBN
Thank you, a photo makes a lot of sense.
But that does not alter the fact that 'numerically' given the ISBN (without the "-")  and the EAN for books after 2007 are the same . Or am I wrong again?

No, that's right.
Fortunately, this does not make the fields superfluous, because many more books were published before that year than after.
