I got a rejected edit (which I was totally fine with because I realized after the fact that I did the wrong thing because the UPC lookup website tricked me) but the thing I expected to get rejected didn't get rejected and the thing I expected to not get rejected got rejected, so I looked at the style guide again and now I'm confused because all of my changes should have been rejected.
BooksBooks generally have ISBN-10, ISBN-13, UPC and occasionally more info. Most listings on the site have Item number populated with the ISBN-13 (Sometimes ISBN-10) value, style guide says this is wrong. Barcode is hit or miss with some listings with ISBN-13 (with ISBN-10 in item number), an actual UPC, or no value. Very rarely do I see description used for ISBN values, which is what the style guide says to do.
Style guide says put ISBN for for barcode, Advanced Style guide says put ISBN in description.
I'm trying to gather what I should be doing. There are cases where strategy guides have ISBN and UPC (seems you'd do ISBN in item number and UPC in barcode) since ISBN is an international standard book number (not company specific, used internationally, is the standard, and is in fact an item number). There are cases where the item has no UPC on the product itself (presumably there is a UPC if you can find a picture of a sealed copy that has the UPC sticker on the cellophane wrapping), which seems like a situation to do ISBN-10 for item number and ISBN-13 for barcode. UPC lookup sites for books like these will list the ISBN-13 as the barcode (

Like honestly, maybe I should've made a new post suggesting a look at how Strategy Guides/Books are handled.
