For quite some time I've been confused between the UPC, EAN, and Barcode Identifying numbers. Quite a few of my submissions have codes on the inside front cover which do no match the ones on the back cover so I've put both in the notes. Well I finally decided to see if I could make sense of the codes. I found a link which explains the difference: https://www.nationwidebarcode.com/are-upc-a-and-ean-13-the-same/
For those who do not want to go to the link, a short summary from the link:
"Before you buy a barcode, we have written this tutorial to help you understand the differences between UPC Barcodes and EAN Barcodes. Below are both an EAN barcode and a UPC Barcode. The EAN contains a 13 digit number and the UPC contains a 12 digit number."
Hope this helps

Thanks, I'll give it a read, I am frequently confused by this!

Hi there,
Not sure if you've already seen in our in-line guidelines, but I made a little guide to help discern the difference between these codes (I was also confused about the differences but learned a lot putting this together). It's not super comprehensive, but for some of the lesser known code types there's an overview of what they usually look like and an example code.
Hope this helps! Let me know if there's anything I could add there that would make it more useful

I did see that but it really didn't make things clear for me. I was confused by the difference between UPC and barcode. My later books identify the the codes inside the front cover by EAN, but the older books don't mention EAN. Not until I encountered a book that identifies the EAN and I counted the # of numerals did I realize the difference.
Also, from a discussion on Discogs, I assume the difference between barcode and UPC is the the barcode is the scanned code and the UPC are the numerals on the label?
Also, any idea what the 'S' in a triangle signifies?

Good job on the guide, I like it.

But I'm not sure the "Library of Congress Call Number" should even be used for our purposes. I believe our use of the "Library of Congress Classification Number" is sufficient. As I understand it, and I could be wrong, a Call Number refers to a single specific copy of a title in a specific library.

The following is from Wikipedia under Library of Congress Classification:

"the classifications may be distinguished from the call numbers assigned to particular copies of books in the collection, such as "PZ7.J684 Wj 1982 FT MEADE Copy 1" where the classification is "PZ7.J684 Wj 1982"."

Following is a link to a specific library's website that discusses their use of call numbers:

https://www.lib.sfu.ca/find/what-call-number

So, I propose we eliminate the Call Number code entirely. And, perhaps we should change the "Library of Congress Classification Number" code's title to just "Library of Congress Classification (LCC)" That could help eliminate possible confusion with the "Library of Congress Catalog Number (LCCN)" code.

Barcode is just an umbrella term, while UPC and EAN are types of barcodes. There are plenty more: https://en.wikipedia.org/wiki/Barcode#Types_of_barcodes

I've used the "Barcode" credit in cases where I can't use any of the other ones, i.e. the barcode doesn't match the UPC or EAN standards (it either has a mistake or is another type of barcode).

Also, any idea what the 'S' in a triangle signifies?

It means the book is "strippable", more information for example here:

Sorry about the duplicate post, not quite sure how that happened.

So the assumption is that on U.S. books the UPC and/or EAN credit is used if it matches the standards even if the label doesn't specifically state "UPC" or "EAN"?
Looks like I'll be going back to make a few changes

Thank You

If you can figure out which one it is, I think you should specify the type.

That said, I don't think it's a huge problem if you have used the "Barcode" option. In the beginning that's all we had, so there are quite a few books in the database that use it - even when the type is specified on the book. Personally I've only updated them when I've had to update something else, but in the end it's up to you. :-)

mjb has written a nice wiki about UPC vs EAN on the Discogs wiki site: https://reference.discogslabs.com/wiki/upc-a-and-ean-13-barcodes

You can get your UPC / EAN barcodes needs from this site. www.barcodescheap.com
They respond quickly to questions, you can get free barcodes to try and they send fast and barcodes registered GS1
I recommend it to those who need it. www.barcodescheap.com

LOL, is that Spam! Aren't they the people you have to use when trying to add a 'new' publication to Amazon?

Me thinks so. If not, it is hardly a Forum topic.

There is a mistake in the guidelines
https://books.discogs.com/guidelines/book#identifying_codes:

ISBN 13
A 13 digit ISBN number, only on books printed after 1 January 2007.>

ISBN 13 was invented in 2005, since 1 January 2007 there is only ISBN 13, no ISBN 10 anymore.

https://www.isbn-international.org/content/what-isbn
https://www.publishers.asn.au/resources/isbn-13-international-standard-book-number
https://en.wikipedia.org/wiki/International_Standard_Book_Number

All of these sources state the introduction of the ISBN-13 was on 1 January 2007.

Maybe it was "invented" in 2005 but not introduced until 2007?

I did some more research and found this:

The 13-digit ISBN was introduced in the fourth edition of ISO standard 2108, of May 2005, to be in use for all new ISBNs from 1st January 2007: https://isbn-information.com/the-13-digit-isbn.html

So it looks like the two systems co-existed for a period between May 2005 and December 2006 with the ISBN-13 completely replacing the ISBN-10 on 1 January 2007.

I agree the Guideline needs a tweak but that is something only the staff can do.
