Important Update: Book Cover Image URL Format Changed

We want to inform ISBNdb customers about the change to the book cover image URL format, which affects how book cover images are accessed through our service.

The old URL format will continue to work until the end of the month, after which these old URLs will cease to function. All API requests now return book cover image URLs in the new format.

If you're storing or caching book cover URLs in your application:

  1. Update your systems to handle the new URL format
  2. Replace any stored old-format URLs with their new equivalents

If you have any questions or need assistance, please contact our support team.
