I noticed that there was a cover mismatch with a coce_amazon cover because the new 2024 title has an ISBN of 9798885795692 (using the 979 instead of 978). There is an Italian title with an ISBN of 8885795692 that is showing instead.
Actually... looking back on Kal's original comment... I'd like to hear some steps on how to reproduce this problem. Because currently Koha will generate an empty "normalized_isbn" value for a ISBN starting with 979, so Koha shouldn't be trying to display any cover images. I just tested in koha-testing-docker and no cover image is even attempted with a record with the 9798885795692 ISBN. So... I'm not sure how this could be happening in Koha. Now I think that we should upgrade Business::ISBN because we do want to support ISBNs starting with 979. I think that will be a bit of work. However, even if we do that, Amazon is still going to be a problem. From past experience, I don't think that Amazon actually supports ISBN-13 at all when it comes to cover images. For example, note that all 3 of these URLs returns the same image. https://images-na.ssl-images-amazon.com/images/P/9798885795692.01.LZZZZZZZ.j... https://images-na.ssl-images-amazon.com/images/P/9788885795692.01.LZZZZZZZ.j... https://images-na.ssl-images-amazon.com/images/P/8885795692.01.LZZZZZZZ.jpg In the past, I think that's why we've used the ISBN-10 version for requesting images from Amazon. ISBN-13 with 979 is going to be a problem for Amazon images in particular. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
